When PJ's old nemesis Luke Darcy (see season 4's ""The Civil Dead"") is freed from jail, he returns to Mount Thomas and PJ instantly believes he is bad news.

After a bashing, and then the rape of Luke's own grandmother, the evidence points elswhere but PJ's suspicions - and the suspicions of Luke's cousin - lead him to force his anger onto Luke.

Meanwhile, Susie and Ben - who have each spent months in therapy - talk about their issue and Susie begins to think Ben is ignoring it, rather than confronting his feelings about killing her husband.

After Luke attempts to rape and kill Jo, PJ angrily heads to his house. When the others arrive they find Luke dead with an axe in the head - and PJ standing over him...

PJ refuses to explain how he came to be standing over the dead body of Luke Darcy, forcing the Homicide Squad to arrest him for murder. The other Heelers must prove his innocence and find the real killer.

Ben has already begun to suspect that he has met his match in selfless self-sacrifice in Marissa, but relations are strained when Ben realises that Marissa is hiding the kids.

While most things work out well, Ben and Marissa soon realise that they don't have the trust to make their marriage work, and decide to call it off.

P.J. and Jo run into a wall of silence when they investigate the allegation that a music teacher employed by the Mt Thomas Brass Band has been having sex with his under age charges. Tom seeks help from his parish priest, who finds himself constrained by a skeleton in his own closet.

Tom has a black eye, PJ and Jo are in a foul temper after a bush walk goes wrong, Ben and Susie are frustrated after they chase a non-crime, and only when Jonesy reveals his adventures with a new Constable in Widgeree does PJ realise that they all hold a piece of the puzzle which may lead to the recovery of a quarter of a million dollars in stolen loot.

Susie and Evan find a young boy near death during a spate of alcohol robberies at the Imperial. Chris injures herself when she chases after the robbers, and Jones, feeling responsible for not coming to her aid when he had the chance, hires another bartender. But is he part of a gang who is forcing alcohol onto the young?

A woman who works out at the same gym as Susie and Jo is raped, and the Heelers suspect the gym owner when a witness cites sexual harassment. When looking through the local Internet sites, Jonesy discovers a porn site that includes the gym rape victims, and to her horror Jo as well. The race is on to find the rapist before Jo becomes his next victim.

On their way to see the new constable who took over the station in Widgeree, Jo and PJ become embroiled in a case that involves aliens, Ned Kelly's saddle and a missing boy. They struggle to find out the truth when even the local police believe they had been abducted.

Tempers flare as a man the town is convinced killed his son returns when the courts find him not guilty. Jo and PJ keep an eye on the lynch mob at the Imperial while Susie, Jonesy and Tom keep the man at the station.

Jo reopens the case of a missing teenager when his mother claims to have seen him in the dead of the night. Jo senses that there is more to the case than she imagined, and soon finds herself involved in a web of lies.

A former AFL player for the Hawthorn Hawks is robbed, and takes an instant liking to Susie when he goes in to report the robbery. Jealous, Evan investigates hoping to prove the former football hero isn't as innocent as he claims.

Susie and Evan make the horrifying discovery of about 50 dead kangaroos, looking to have been ripped apart with an automatic rifle. As debates rage over whether or not to thin out kangaroo numbers, the farmer who owns the land where the dead roos were found comes under suspicion. He denies it and suggests a mate he served with in Vietnam might be responsible for it, thinking that slaughtering the kangaroos might send a message to not have a cull. As the Heelers dig deeper, it is discovered that a cache of weapons from Vietnam had been kept, but when they come to seize them, some turn up missing. Now the race is on to find the weapons and whoever might be holding them.

Jonesy and Susie head to the site of an ecstasy overdose only to discover Jonesy's young brother Dylan, with the Drug Squad, got there first. Dylan loves to snub his brother because of their positions and soon leads an investigation into drugs in Mt. Thomas without listening to Jonesy's evidence. Jones goes after a brother and sister pair who he suspects, even though they are Dylan's friends, and his vigilance has even Susie convinced that he is just doing it to beat his brother. Meanwhile, a surprise 30th birthday party for Jonesy comes to a head when he fights with his brother, and they are seen fighting by Tom and Commander Jones - the boys' father. Later, Dylan collapses on the dance floor...

Dylan dies of an ecstasy overdose, after convincing his father that he doesn't take drugs, and it was Jonesy's fault. Susie enlists PJ's help to see whether it was Dylan's friends or his colleague who spiked his drink. Although Jonesy tries to keep his family name clean, his father soon suspects him of being on drugs and Inspector Monica Draper arrives to investigate. So when Jonesy finds evidence that his brother himself was on drugs, he is torn as to whether he should take the fall, or reveal what his late brother was really like.

A middle aged doctor is murdered on the morning he is supposed to give testimony and Jo - having her own personal dilemmas because she fears that she has fallen pregnant to PJ - is emotionally thrown by the case. When she withholds vital information, however, Susie starts to worry.

A bungled police raid leaves Ben shot in the arm by Susie and a formal investigation looks set to find her guilty of shooting him out of payback for her husband's death last year rather than an accident, even though the Heelers are sure that she is innocent.

It seems a usual day at the office: Tom's fishing trip is yet again interrupted by Grace's job, PJ and Jo have decided that its time to tie the knot, and the usual slew of cases are coming in the door.

However bliss gives way to suspicion when an old case drags up Maggie's memory and PJ begins to question his feelings for Jo. When PJ has to talk to a teenage girl to stop her from jumping, he reveals what he really thinks, leading to a shocking blow for Jo...

After an old lady is mugged, tension builds in Mt. Thomas. Thanks to Clancy, an eye-witness of the event, suspicion rests on a new family in town: the Baxters. The adult children, Matt, Troy and Tarni are brought in but nothing can be proven. Their father Barry, a softly controlling man, comes to bail them out and shortly afterward, Clancy is bashed.

The cops link it back to the Baxters and end up arresting Troy when a brick is thrown through Tom's window. However, at the same time, an old war veteran named 'Rocket' Turnbull who served with Tom is in town, and has publicly threatened Tom.

Meanwhile, Ben is attempting to play relationship advisor with Jo and PJ, until she confesses to him that the reason they split is because of Maggie. PJ thinks they can still work together, but Jo has asked for a transfer.

A new day dawns in Mt. Thomas. Grace and Jo are distraught when Cal Millic, a man who they were helping in a custody battle, loses, and refuses to give his daughter back. Jo is forc

It is the day after the explosion. The Mt. Thomas police station lies in ruins; Senior Constable Joanna Parish is dead, as is Clancy Freeman; and Grace Croydon is missing. While Tom recovers in hospital, PJ, Ben, Susie and Jonesy move into the new police premises where they are met with a surprise: Nick Schultz, now a Detective Sergeant in Homicide, has arrived to investigate the attack. And he's not the only one.

Sergeant Mark Jacobs has arrived in town for a temporary post - or so he thinks. But Inspector Falcon-Price wants Jacobs to move permanently into Mt. Thomas, because he wants a person more suitable than Ben to take over when Tom retires. Jacobs is an intellectual, self-confident, ambitious man in his 40s and quickly shows authority as the group move into their new premises.

PJ and Nick question 'Rocket' Turnbull, Tom's old war comrade, although he claims - and Tom agrees - that he couldn't get access to that much explosive.

When Cal Millic - the father who threatened Jo shor

Troy Baxter has been crushed underneath a car at his property. Barry blames Tom and, while most of the cops brush this off as grief, Nick thinks it may be true. As Jonesy, Ben and Susie move things in to the new station, PJ and Nick focus on Cal Millic, who Tom thinks is just a distraction. Probationary Constable Kelly O'Rourke arrives. She's fresh from the Academy, ambitious and enthusiastic, and determined to prove her worth. Her father, who was an old friend of Tom's, died in the course of his duty as a policeman. However, her attempts to convey her sympathy to Tom end in him disciplining her. She is quickly aware that Tom Croydon is a changed man.

Grace's autopsy report comes back: she was raped before, presumably, struggling to escape and falling into the river, where she drowned. Tom wants it kept out of the press, but it has already appeared on the radio. Jonesy and Susie pull over a speeder and discover it is Probationary Constable Joss Peroni. He's an enthusiastic cowboy who l

Barry Baxter is on assault charges against Tom, and Chris is angry because she was forced to lie for Tom. She confronts him and then tells Susie that Tom needs help.

Before Susie can process this, however, she discovers a suspicious package in the foyer, and the cops evacuate. It is revealed as a false alarm, and a simple extortion tactic from a man in need of money, but the threat only heightens the panic in Mt. Thomas.

Chris is attacked at the pub by a girl on speed, and Jonesy is interested to know who sold it to her. But the investigation quickly becomes overshadowed by the other events in town.

Mark, Joss and Kelly begin to get used to the life of Mt. Thomas when they investigate an alleged break-in, only to discover that the culprit was an injured joey.

PJ and Nick desperately attempt to prove Cal Millic is the bomber, and the media agrees with them. Millic begins to crack under the pressure of public opinion, but the situation only ends in tragedy when Millic takes his young dau

Tension is rife in Mt. Thomas. Joss and Kelly interrupt a girl who goes crazy in a store, and later find out that bad speed is being sold in the town. PJ and Nick are on bad terms over what they think of Tom's intentions, and Amy is just trying to get someone to let her help. Ben and Susie are acting professionally around each other, and Jonesy is annoyed about their dalliance.

After clearing up the confusion about which Sergeant is for what (Ben is for Operations, Mark is for Administration), the DNA report comes back which concludes that Troy Baxter did meddle with Grace's car but, to prove he raped Grace, they must stop the funeral and take his body for DNA, which angers the Baxter family.

Although it is proven that Troy did rape Grace, PJ begins to side with Nick that Tom may be overdoing it to suggest that the Baxters bombed the station. And - after Tom verbally assaults Barry Baxter - and suggests they are selling speed as well, PJ earnestly believes he has gone over the edge. In

The gruelling investigation of the attacks on the Mt. Thomas police continues, as Tom heads to Melbourne to investigate the man who sold the parts for the bomb. He links it to chemical dealer 'Doc' Parkinson, and is determined to prove that he provided the Baxters with supplies for both the bomb and the speed.

Although Nick seems to be against this idea, he does join PJ and Amy - who everyone at the station is very impressed with - on another search of the Baxter property, during which time he plants listening devices in their home - which ultimately lead them to discover the truth.

On a doorknock, Jonesy and Susie rescue an attractive woman named Donna from a rubbish skip she has been locked in, and Jonesy falls for her. That night at the pub, her former de facto lover hits him, and then claims that Donna took all his possessions, and is a con artist.

Ben has been fawning over Susie a little too much, buying her expensive gifts, and she ultimately gives them back and leaves him unsure

Despite allegations by her ex-boyfriend Theo that she isn't all she appears to be, Jonesy stays firm to Donna in trying to protect her. She soon moves in with him.

Only Susie is suspicious of Donna, a suspicion seemingly confirmed when Jonesy's room is trashed. He arrests Theo, whom Amy recognises from her time in Melbourne - he was involved in an assault on a known drug dealer. Tom agrees with Amy, and refuses to give Donna police protection since she may be involved.

Jonesy is not happy, pleading with the others and ultimately storming out of the station to go and personally protect Donna. The cops begin to consider that they've gone too far, but a defiant Tom stands firm - Jonesy had better come back, or he'll be out of a job...

Jonesy finds his career on the line as he attempts to protect Donna, and so he is stunned when he learns that she is a call girl. When they are attacked by Theo, and Jonesy claims that Donna was abducted, Amy soon doubts his theory - thinking that Donna faked her abduction. Susie soon joins in on this theory, after Donna tells her that she has Jonesy now, and Susie can never have him back.

Although Jonesy is allowed to return to work, and attempts to patch things up with the others, he is still seeing Donna - and is stunned when she tells him that a missing man named Hugo Allen was killed by Theo, and that Theo is actually a hired hitman.

Jonesy is stunned when Donna tells him that the people who hired Theo to kill Hugo Allen were in fact the police of St. David's. As he goes about investigating secretly, he learns that the police have not been caring about Allen's disappearance. When Amy finds out about his investigation, he is forced to get Donna to talk to her.

Donna confesses that Louis Chang, a restaurant owner in St. David's, runs an illegal casino from his restaurant and she was a call girl there. She was with Hugo when he found himself in trouble with Chang, and subsequently Chang had his police buddies order Hugo's death. She had a mobile phone with pictures of the casino on it, but it was stolen when Jonesy's room was ransacked.

Amy believes Donna's story, but decides not to tell Tom in case he, too, is corrupt. Jonesy and Amy go to Chang's posing as a dating couple, but are interrupted by Inspector Falcon-Price and St David's multicultural police liaison Lucy Wu, who are also dining there. Jonesy suspects tha

Donna is once again missing, but this time when she turns up she is high on cocaine, and Amy and Susie are desperate to know where she got it from.

Meanwhile, Chris attempts to get someone to listen to her when she suspects there is a person hiding in her pub, and late one night she and Joss investigate and discover her ex-husband, Terry Kennedy, in the cellar. Kennedy came through decades earlier with his shearing mates and married Chris while she was still the publican's daughter, before eventually running off. She wants him out of town, and Tom agrees.

The rest of the station is busy as usual: the disappearance of a pig and a dog causes an uproar; Ben and Susie - who appear to have begun a sexual relationship - seem to be at odds over where they are going next: Ben clearly wanting to go further, Susie not so sure; and Lucy Wu has been popping up at the station.

An angry Jonesy goes to see Louis Chang but gets nothing out of him, however later the mobile phone with pictures of the il

Jonesy is missing, and the general consensus is that he has run off with Donna. Only Susie is suspicious, and rightly so - since he has been shot and wounded, and finds himself being held captive by Louis Chang.

Tom is at first unwilling to believe Susie, and is too busy with the investigation into police corruption into St. David's.

Frustrated, Susie has no choice but to go undercover unoficially and Ben - of course - agrees to help her.

Tom and the team investigate Inspector Falcon-Price but the evidence soon proves that he isn't guilty, and neither is Lucy Wu - who both Amy and Jonesy were suspicious of.

As the day comes to a climax, Susie and Ben find themselves in a dangerous situation which they survive, but she ultimately breaks up with him. Jonesy has to do the same to Donna, and has her arrested. And Amy is stunned to learn that her friend Andrew Reid is the real corrupt cop at St. David's.

Mt. Thomas is inundated by a group of footballers, and it isn't long before a gang rape occurs, but what no one expects is for Tom's stepson Daniel to be implicated. Amy, in particular, seems to be particularly emotionally involved with the rape case.

Meanwhile, Ben starts a dangerous spiral as he realises that Susie has truly rejected him, and he convinces himself that he is a failure as a policeman.

While Ben contemplates suicide, he ultimately makes a noble choice by resigning and going to be with his children in Perth.

As the rape investigation continues, Inspector Draper arrives in town - worried that Tom is running amok. While Daniel evantually agrees to a DNA test, and is proven innocent, Tom loses his stepsons as they leave to live with their grandparents.

Meanwhile, Joss, Jonesy and Kelly deal with a snake problem.

Sgt. Roy Holland arrives in town and Joss takes the opportunity to get on his good side and do more than paperwork. While Joss investigates a mother who gave birth on the side of the road but soon is suspected of lying; Kelly bonds with Roy, who worked with her father as young cops. But soon things get out of hand when he makes a sexual pass at her.

Jonesy finds himself against the law again when a friend of his is accused of murder.

Kelly's rejection of Sgt. Holland sees him treating her badly and continually giving her abuse. Amy realises what has happened but Kelly won't put in a complaint.

When she finally does end up deciding to tell Tom, it is too late - for Roy's heroic actions in saving a suicidal kid from a deadly situation have made him a hero.

Meanwhile, after rescuing an attractive older woman from a bicycle accident, Joss and Roy recieve a dinner invitation which ends unexpectedly; and PJ and Susie suspect an inside job when they investigate a robbery at a veterinary clinic and end up unravelling a deep family secret.

Joss discovers that Fay has a jealous husband and decides to break it off, until she makes him an offer; after a difficult confrontation, Kelly confides in Susie about Roy - leading to their decision to teach him a lesson; and PJ and Amy comes to loggerheads over who to arrest in a burglary and arson investigation.

Joss attempts to break things off with Fay Tudor but she doesn't agree. What he soon realises however, is that he is attempting to break off with her because he actually likes the relationship for once.

Kelly is riding high after she gets payback on sleazy Sergeant Holland, but it isn't long before he is trying his old tricks on another young woman named Shayleen, who is only 15.

Tarni Baxter returns to town, and Tom is certain that she is desperate for vengeance after Tom's arrest of her family. While he and Tarni square off, he arrests her boyfriend Ryan for possession of drugs, only Mark is suspicious that he planted the drugs himself. Tom arrives home that afternoon to find his dog, Digger, viciously murdered.

Kelly realises that Roy is dangerous and makes a formal complaint to Tom, who agrees with her and suspends Roy, who then threatens him.

The next day Tom's rental car is found on a deserted road, completely destroyed by fire - and with a charred body at the wheel.

The cops attempt to come to terms with what appears to be Tom's death.

Amy suspects suicide but PJ thinks otherwise and, upon learning that Tarni Baxter had no idea of the accident, the two are set back a bit as to who committed the murder. What they don't expect is to find Tom alive in a seedy hotel, and although they attempt to help him, they soon realise that he may have been responsible for the death of whoever it was in his car.

PJ and Kelly attempt to prove Tom's innocence but Amy and Roy think he may have gone over the edge. When they discover that Roy Holland is missing, it becomes likely that his body was in the car, and the knowledge that Tom suspended him, and that Roy may have suspected Tom of planting drugs on Ryan Dekker, leads Mark to accuse Tom of murder.

Tom, meanwhile, is crazy with rage. He threatens Tarni by promising to plant her hair on the car and implicate her. However Shayleen Burke soon confesses that her father killed Roy after he discovered everything about

It has been eight weeks since Tom pushed Tarni underwater, and he is now the subject of a possible murder investigation.

Mark is running the station, with Tom suspended, and the new Acting Sergeant Lindy Schroder is intriguing everyone - particularly Joss. Nick is in town to help PJ investigate the case during which time they have learnt that Tarni survived Tom's attempt on her life, and claims Tom then killed Ryan and fled. Tom, however, claims, he never found Tarni, and he was shot at as he left the premises after tying Ryan up. However, Ryan's death does seem to be the work of one of them.

While Joss and Jonesy are stuck investigating the arson of a set of bonsai trees, Amy investigates a video store robbery using the same rifle as the one that killed Ryan. When it leads to a friend of Ryan's and Tarni's, it seems to prove that they were involved in Ryan's death but the coroner, and lead investigator Greta Conroy, think otherwise, and Tom is formerly charged with murder.

Tom has been formerly charged with murder, and he seems unwilling to even help PJ and Nick find the truth, even though they also believe that Tarni Baxter has something that she's hiding. But when Kelly is kidnapped, they must attempt to convince Tom to help them rescue her and in doing so, prove his innocence.

Meanwhile, Amy attempts to get rid of a case that is annoying her by passing it on to anyone who will take it; and Joss learns more about Lindy Schroder, who was given the position at the station because she is a friend of Mark's.

The Heelers settle into an unusual routine when Tom returns to the station and reclaims his position as Boss. While some are more willing than others to accept it, Lindy discovers that Tom is not going to make things easy for her. As it is, Tom doesn't think much of Mark, who isn't the type of cop he is interested in, and he makes things even harder for the new cop in town.

While Lindy finds her job in jeopardy, PJ, Amy, Joss and Kelly find themselves investigating bizarre cases - this is no normal week in Mt. Thomas.

After the second SIDS related death in as many weeks occurs, PJ and Amy grow suspicious and investigate, only to find the town turning against them in its grief.

Investigating a problem at the Imperial, Kelly is amused when Chris informs her that Joss has moved out to live with friends, and she forwards his mother's ""care packages"" to the station.

Meanwhile Jonesy and Susie are held hostage and are saved by Senior Constable Alex Kirby - Lindy's replacement, and an old friend of Jonesy's.

After a home invasion strikes Mt. Thomas, PJ, Amy and Tom comfort the grieving O'Keefe family. What they don't expect is to learn that the father, Danny, has gangster connections and this isn't going down well with Tom's current attitude.

And Susie is forced to bond with Alex, who is enjoying it immensely, when Jonesy is involved in a car chase with tragic results.

Raynor and Kirby investigate a reportedly missing girl that has everything she could ever want. But it seems she has been corresponding with an older male, and he may be ther eason behind her disappearance.

Joss and Kelly also try to restart the bluelight basketball team. Kelly discovers one boy in the team had been dealing drugs. Joss gets the team interested in soccer and decides to set up a soccer club. He invites his brother to help. Toni then tries to seduce kelly.

Tom also decides it is time to get something on Danny O'Keefe and instructs them to haul him in over anything. Kelly does and Tom is delighted. They can't get anything on him. PJ returns from a conference then Tom says he's going out. PJ needs to go again and tells Amy something more important has come up. PJ finds Tom at the soccer club next to Mr O'Keefe's car which has a broken window. PJ calms the storm then asks if Mr O'Keefe wants to press charges. PJ and Tom convince him not to.

A father disowning his newborn baby leads Alex and Susie to suspect the mother, a schoolteacher, has been having an affair with a 14 year old schoolboy.

At first both parties deny a relationship, but when they run away together, the case is all but proven, it seems the realtionship has been going on since the boy was 13. On his 13th birthday in fact.

Meanwhile Joss feels sorry for a drunk he and Kelly find in the street and returns him home instead of charging him, overcoming the reluctance of his Russian speaking mother. Next day he finds himself in front of Tom—it turns out the drunk was completely unknown to the woman.

Meanwhile, Alex and Susie are on a stakeout when Alex makes a move on her. Susie ends up sleeping with him, and seems to have fallen for him. The next day, though, Alex learns that Jonesy does like Susie - despite his protestrations - and so Alex makes the decision to back off.

When the school teacher's husband comes to collect his wife and the newborn baby, it ends i

After a sex offender escapes from prison, Jonesy attempts to help a terrified family find their young daughter; Kelly vows - with Joss's help - to find prove the sexual assault of a female shop assistant; and when the escaped prisoner is accused of murder, Amy finds she will be working with a former boyfriend - Homicide Detective Garth Henderson.

Their investigation becomes more complicated, however, when a body is found brutally murdered at Govett's Leap...

Tragedy turns to terror in Mt. Thomas when a second body is found, killed in a similar manner to the first one, and with a crucifix by the body as before. It appears there is a serial killer in town.

PJ and Amy work with Garth to track down the only man with links to both girls - a masseuse who seems to fit their profile. But, while in questioning, a third victim is found giving the masseuse an alibi.

What confuses the detectives is that the third victim is male which doesn't fit with their established profile of the killer, and it seems they must start at square one.

Meanwhile a recently promoted Senior Constable Susie finds Jonesy is jealous of her promotion, since he too is waiting for one; and Joss and Kelly deal with a child whose dog's burn injuries have aroused suspicion at the local vet.

The third victim of the Mt. Thomas serial killer is a gay teacher named Leon Barclay. PJ and Amy discover a link between him and the second victim - Merinda May: a therapy group for sexual abuse victims, run by Dr. Bill Lapscott a psychologist. What makes them worried about this link is that the first victim did not attend, so Amy infiltrates the group to see if this could be how the victims were chosen.

As the group share stories of their own sexual abuses, Amy gives one also. While she later insists she was making it up, Bill recognises the signs and knows that she wasn't. He invites her out, and begins getting to know her. Garth, however, begins to spect that Bill himself is the killer - a theory that seems cemented when they learn that Bill lived in the same street as Janelle Watts, the first victim.

Amy doesn't believe this theory, so she desperately tries to prove otherwise and ends up suspecting Jeff - Janelle's father - as being the killer.

Meanwhile, Bill asks Amy out and they

The fourth victim of the Mt. Thomas killer has been found in an alleyway near Bill Lapscott's house, using what looks to have been a brick from his yard to knock her out. Confusing the detectives is the fact that a different weapon was used in what seems almost to be a different M.O. The only thing tying her to the other victims is the crucifix, and her history of sexual abuse, leading Garth to suspect there is a copycat killer at work. Amy's theory that Jeff Watts is the killer is proven wrong, since he was under surveillance, but Garth suspects it was Bill. They find him, still at the office, having showered. But there is no evidence to link him to the crimes, since his clothes have no blood on them.

Day Six. Searching Ngaire's house, Garth finds a love letter from her to Bill. He claims that he looked after her one night when she was suicidal and she developed a crush on him, which he did not reciprocate. Recognising Garth's own issues, Bill tells him to go to therapy and Garth gets

The terror in Mt. Thomas reaches climax point as the serial killer strikes out at Amy. She survived one attack, but knows that whoever it is will kill again before the day is through. And PJ, still certain that the killer is Garth, is forced to prove or disprove his case to stop the killer before he kills again...

Susie starts a crusade to clear the name of a man accused of an attempted mass murder, by leaving a bomb at the hospital. Unfortunately her task is made harder by the fact that the man killed himself on that same day.

Meanwhile, suspecting that her change in mood equals feelings toward him, Jonesy plucks up the courage to ask her out, and recieves a bit of a surprise...

After a failure on Mark's part, Tom blasts the team for their lack of protocol when Susie is suspected of theft by an elderly woman, and Alex is the only one who can prove her innocence.

During a soccer game, Butch O'Keefe - Danny O'Keefe's son - is involved in a feud which escalates when guns are brought in, and Jonesy is caught up in it. Tom becomes suspicious when an old associate of Danny's from the underworld shows up in Mt. Thomas, and has all the cops put on alert. But out of nowhere, the real source of trouble in town is revealed...

With Jonesy deeply involved in the honour killings in Mt. Thomas, and Tom completely off the rails trying to stop Danny O'Keefe, the station verges on utter chaos.

PJ is concerned by Amy's over-reaction when she is confronted by someone from her past. He encourages Amy to face the reason for her behaviour - renewed contact with the family of the uncle who sexually abused her as a child.

Elsewhere, Mark's actions involving a load of stolen tobacco infuriate Tom, and as Inspector Falcon-Price is brought in to the middle of the heightening feud, the tension continues climbing...

Tensions continue to rise in Mt. Thomas, as Amy deals with her past and the power struggle for the station continues.

Amy confronts her uncle with the support of PJ but is her memory tricking her?

Tom faces the spectre of Barry Baxter, the man who killed his wife. Escaping from court on the first day of his trial, Baxter closes in on Mt Thomas, causing Tom to fear for the safety of his grandchildren. Meanwhile, Jonesy finally proposes to Susie but how will he react when he learns the truth about Susie and Alex?

With Tom's two grandchildren held hostage Barry Baxter ives Tom one final ultimatium. Can Tom save the lives of his grandcildren and one of his colleages

Jonesy is dismayed when Susie hits it off with a handsome victim of a car theft racket that the Heelers are trying to crack. Feeling rejected, foolhardy Jonesy risks his life in a ute surfing competition as he tries to salvage the lives of a young man and his pregnant sister. Meanwhile, Joss uses his BMW as bait for car thieves, but loses it another way.

Out on a night-long patrol, Jonesy and Alex are called to a noisy private party. Arriving at the bash, the Heelers soon realise they've come to the home of Jason Tyler, the new boyfriend of Jonesy's ex-love and police colleague, Susie.

Joss and Kelly's birthday celebrations are soured when one of the guests, a lifelong friend of Kelly's, is found dead — the victim of an apparent drug overdose. The preliminary autopsy report reveals that she'd had sex a short time before her death, but Kelly staunchly maintains that her engaged friend was neither promiscuous nor a drug user.

Three popular teenagers are killed in an horrific highway collision with a truck and there are conflicting stories about the final seconds before impact. The whole town wants to believe that the teenagers were murdered by a reckless truck driver, but Amy Fox has to deal with the fact that the truck driver is her cousin.

Alex's good nature makes him an enemy. The man who killed Kelly's father 15 years ago has been released from prison and is in town to tend to his dying mother. A wall of sympathy and police solidarity is thrown up around Kelly. Tom takes steps to run the released killer out of town, but Alex earns the resentment of his colleagues by treating the man fairly.

Mark feels guilty and depressed when the lost teenage girl he handed back to her family is found murdered just hours later.

The paddock at the lonely Biden farm has revealed the remains of three more murder victims, all teenage girls. Charlie Biden has already admitted to killing one, and is clearly the murderer of the others. His wife, Marie, frustratingly takes the high moral ground, until Charlie dies violently in custody, obviously by means of Marie. Mark takes the blame for this death as well and spins further into despair.

An after-hours robbery of the Imperial Hotel is interrupted by the publican, Chris Riley. There is a struggle in the darkened bar, and Chris is left with a badly cut hand and a young female robber in a coma from a blow to the head.

Alex continues a struggle with paranoia after receiving a bullet taped to a transfer application form. Things become more desperate when petty criminal Terry Swanson exploits Alex's situation by involving the police bureaucracy, further inflaming tensions inside the Mt Thomas station. Joss, the one person who can remedy all this, lacks the courage to confront Alex or confess to the boss.

Alex's belief that he is being victimised by his colleagues, and the media attention he is attracting, widens the trust gap felt by the police of Mt Thomas. Alex rejects offers of help and understanding from Jonesy, preferring to fight a losing battle against his idea of injustice. Joss is convinced he will be sacked for starting the whole thing, and drags his feet to avoid the inevitable confrontation with the boss.

Tom confronts his past when an old army mate confesses to a 35-year-old homicide. As the horrific nature of the crime is discovered, Tom begins to question the truth of his friend's confession. Amy challenges Tom over his involvement in the murder investigation and discovers he had a close personal involvement with the victim.

Amy and Jonesy investigate when a recent lotto winner is found bashed and near death on a country road. They suspect his two gold-digging mates. What they don't expect is an admission that they were taking part in an assisted suicide. But what made the man with everything to live for want to die?

On a Saturday morning, after the high school Formal, Amy and Jonesy investigate the death of a teenage girl, murdered, apparently by her friends.

Matt's ruthless approach to truth and justice seems so black and white to Alex that even the victims of crime must have judgement brought upon them. But Matt's way of dealing with a young man who has attacked his teacher shows he may be equally as capable of dealing with an emotionally driven criminal situation as Alex. Kelly tries to sever ties with her stalker, but finds the obsession is just beginning.

Matt's army service in East Timor complicates his dealings with a man who robs a video store. Amy follows up the latest sighting by a frantic mother still seeking the driver responsible for a fatal hit-and-run that killed her daughter. Kelly cannot ignore Estelle White, the young woman who is obsessed with her.

As Amy and Jonesy investigate a grisly murder, Matt forges ahead with his own line of inquiry. The growing suspicion surrounding the new constable appears justified when Matt's chief suspect is mysteriously murdered. Amy is faced with the prospect that one of the Heelers has crossed the line.

Matt's military past is revealed as he is investigated by his peers in relation to a murder, while Amy grudgingly notes Jonesy's potential as a detective. Meanwhile, suffering from post-traumatic stress, Kelly makes a serious error in judgement which leads to a harrowing showdown with her number one fan.

Matt finds a seriously battered man, the former mayor of St Davids, in the boot of a stolen car after a high speed chase. Mt Thomas CI investigates, but with Jonesy away at detective's training school, Amy finds good help hard to find. She strongly disapproves of Matt's aggressive approach to questioning witnesses, but who can she turn to? Kelly is too messy, Susie too nice, and Joss — well...

On his first day on the job Jonesy discovers that being a detective is harder, and more expensive, than he thought. When a woman alleges she was raped while under general anaesthetic, Jonesy fails to make any headway in the case forcing Amy to get involved to show him how it's done. Pushed out of the rape investigation, Jonesy focuses on solving a burglery at the home of a psychiatrist.

Amy initiates a deadly game of cat and mouse with the accused doctor. Despite Jonesy's warnings, she accepts a lunch invitation only to discover the he has a son with Downs Syndrome and doesn't appear to be quite the monster she had imagined. Amy traces the boy's mother and uncovers the doctor's first victim, but just as she is about to put the doctor away, he again turns the table on her.

Tom, who is not well and is trying to hide it from his colleagues, meets an old friend who has been caught shoplifting and discovers that he was trying to please his ten-year-old daughter who is dying from leukaemia. Tom continues to refuse to see a doctor. Alex is struggling with the idea of being a father, and is further discouraged when his son, Rory, goes missing and is feared kidnapped by gunmen who've been taking shots at uniformed police officers. Finally, the Heelers find that the gunman was taking revenge on the police for the death of his son.

The Heelers are concerned about Tom's health and, despite Amy's nagging, Tom is still very reluctant to see a doctor and denies claims that he is unwell. In the midst of this, Tom becomes personally involved in the case of a young boy who is being bullied and tormented by his peers; this forces Tom to reminisce about his troubles as a child. Matt helps an old colleague of Tom's when he arrives at the station seeking help with an old case.

Tom's health is further declining and he finally gives in to Amy's persistence and opens up to her. Jonesy and Alex become mixed up in a mysterious cult after they find a baby's remains in a firepit in the national park. Alex continues to struggle with the idea of fatherhood and is further discouraged when he makes a mistake that lands Rory in hospital. An elderly man is arrested for shoplifting various items which he intends to give to his girlfriend.

Tom secretly goes to Melbourne to receive treatment for his cancer, confiding only in Amy. Kelly, becoming uneasy about Tom's disappearance, consults Amy who ensures her Tom is out innocently fishing. Following Tom's disappearance, Inspector Falcon-Price gleefully takes over the operation of the station and also becomes suspicious about Tom's whereabouts, finally deciding to question Kelly. Amy begins to get frustrated when the Inspector does his utmost best to hinder her case of a brutal home invasion and assault. When hers and the Inspector's opinions begin to differ, Amy finds herself taken off the case. Alex, in a bid to keep Rory hidden from the Inspector, sends him out on the road with Susie and is terrified when he again goes missing.

Joss comes up with yet another money-making scheme and catches the gambling bug when a pickpocket victim he and Kelly help gives him a winning tip. Jonesy looks into a string of assaults at the local racetrack. Alex and Matt disagree when Alex plans to let a businessman slide on a shoplifting charge and Matt wants to play things by the book. Matt continually maintains that the shoplifter is planning something bigger and even goes to the extent of investigating him on his day off. After his treatment, Tom is forced to accept help from good friends as he recovers from his operation.

Falcon-Price is still at Mount Thomas and, after realising the extent of Tom's bad health, orders him out on the road as Divisional Patrol Supervisor, seeing a chance to get rid of Tom by proving he is not fit for active duty. It looks as if this is true when Alex is stabbed by an escaped offender and it looks as if Tom is to blame. Falcon-Price convinces Alex to have Tom brought before the Medical Officer and, when Alex agrees, Falcon-Price uses this as ammunition to get Tom out of the force; but gets it blown up back in his face. Meanwhile, Jonesy and Amy are have difficulty finding their suspect and Kelly's jealousy is showing when she tries to find some negative information about Joss's new girlfriend.

Joss's mother arrives in Mount Thomas and reveals she is worried about Joss's money habits. Joss reveals he has a gambling problem. While investigating a series of arsons, Kelly gets involved with a lawyer but questions the relationship when it comes to their conflicting interests in differing senses of ethic.

The Heelers investigate the suspicious downing of a crop dusting plane, suspecting sabotage; they just do not count of the amount of suspects. Everyone is concerned that Joss has lost his nerve when he fails to back Kelly up during two incidents. Joss's gambling problems are increasing and his gambling problems start to affect his work. When he is left homeless, Kelly offers him accommodation. Again, Kelly is having problems with her new lawyer boyfriend and the ethical problems that their relationship is presenting. Alex fears for his son when he provides evidence about a robbery. Alex also fears Rory has a crush on Susie, or even worse, that Susie is the one with a crush.

Joss's gambling debts peak; in an attempt to pay them off, he takes a second job as a cab driver. He is presented with a once only opportunity for easy money when a high roller offers him a job as a getaway driver. Amy and Jonesy investigate the murder of a client of Joss's and link it to an armed robbery and Joss's high roller client. Following this, Joss is taken hostage and it becomes a race against time to save him. Kelly's relationship is again tested when she and her boyfriend are again on opposing sides of a case.

Amy and Even are attempting an undercover operating when their cover is blown and Matt is almost shot. Tom is still battling with, and coming to terms with, his cancer and knows that he should be taking his time and renewing ties with his estranged family. He is distracted when disgraced former police-officer Adam Cooper arrives in Mount Thomas, as a photocopier technician. Cooper, who was dismissed by Tom for corruption, attempts to frame Tom and accuses him of illegally selling stolen firearms following the bombing of the former Mount Thomas police station; these are accusations that Inspector Falcon-Price is gleeful to hear and he readily accepts them and grants Cooper anything he desires. Tom also helps fellow cancer suffer, Gina, in her final days and Heelers are left to pick up the pieces. Alex and Amy must prepare for Tom's approaching case, which he seems to have no care for at all, and they are stretched to breaking point. After the accusations against Tom, the Inspector announces that the Mount Thomas station is to close and the Heelers start to find new jobs, facing the fact that they must leave Mount Thomas. Finally, Cooper's scheme is foiled, it is announced that the station is to remain open and the Inspector leaves, very disappointed.
