It's opening day at Spatz, London’s latest fast-food sensation. But with only 4 hours to go, the manager, TJ Strickland, has much on his plate: the building is half finished and short-staffed, and Mrs. Frapelli, the owner’s wife, is about to arrive for the grand ribbon-opening ceremony featuring no ribbon and nothing to cut it with. Yet there’s even more chaos on the menu when an uninvited guest turns up and tries to put a squeeze on the festivities

Heavy metal man Vince Powers quickly changes his tune when he realises that the girl he’s got a crush on, Chloe, is a Mozart freak. Music of another sort is driving the staff out of their minds – it’s the brain-numbingly jolly Spatz jingle which Karen has had committed to a loop tape and insists on playing all day long. Meanwhile a customer called Mr. Fox loses his wallet at the same time as Vince becomes inexplicably well-off.

Toni Gordon is a girl with a problem. Two problems, actually: one, her mother and two, her father. The reason? In a moment of crisis and low self-esteem she wrote and told her Scottish parents that she's been promoted to the position of manager at Spatz. When Mr. and Mrs. Gordon unexpectedly turn up, Toni's forced to take control of the situation – and the restaurant. Meanwhile, Dexter loses all control in his bid to be the first employee to sell 500 hamburgers and win a corporate trip to Paris

Karen takes a tip from the Spatz Tokyo outlet and introduces an early morning exercise programme designed to keep the hard-pressed staff on their toes. After Karen has publicly humiliated Vince and Jo during one of the workouts, the duo get together and not only discover that it's Karen’s birthday, but also that she has had a 'nose job'. They decide to organise a knees-up their boss will never forget (including a birthday card with Pinocchio on and full of nose-related puns). Meanwhile, TJ is on crutches after pulling a muscle at the exercise class and now lives in horror at the prospect of letting down his hockey team

While Karen racks her brains dreaming up yet more publicity gimmicks, TJ's much-derided first aid class gets a shot in the arm when Lily uses what she learnt to save a choking customer's life. Karen quickly sees a chance for some free newspaper coverage and plans to exploit Lily's heroic action for all its worth. There's just one problem: Lily adamantly refuses to cooperate because her dad has no idea she’s working here and would be appalled if he did. But when did Karen ever take no for an answer?

Dexter sets his sights high when TV soap star Cindy Stewart blows in for a bite at the restaurant. The question is, will she swallow fast-talking Dexter's outrageous claim that he's not really a greasy nobody but is in fact the son of the Senegalese ambassador? Meanwhile, TJ is having major pay-cheque problems when the central Spatz computer goes haywire and issues a grave announcement – that TJ is dead.'

A gang of teenage hoodlums starts hanging around the restaurant and Karen orders TJ to get rid of them. But when the self-styled Diablos return it's with revenge on their minds. When it is revealed that Vince used to belong to the gang, his loyalties are sorely tested as he comes to wrestle with the problem.

A protest group calling itself Planetwatch pickets the restaurant, ruining Karen's quarterly profit figures. It may be friendly to the environment, but Planetwatch is downright hostile to Spatz – that is, until its ringleader Sebastian gets the hots for Jo. It takes a special package, sent from Granny Strickland to TJ, finally to give the protesters some food for thought

TJ conjures up a plan for Spatz to host kids' parties and reckons he’s come up with a wizard scheme. But as usual (since it wasn't her idea) Karen is deeply unimpressed and soon the whole enterprise seems doomed to failure. But when Head Office green-lights the project and commends TJ for his initiative, Karen sees red and decides to sink the party plan once and for all. Meanwhile, the staff work their magic on Stanley to get him ready for his first date.

The staff of Spatz is revolting. When Vince discovers that rival hamburger chain Blimpy's is paying their staff 10p more an hour than Spatz, it's a case of down with the pickle choppers and up with the workers when Karen lets it be known that she'd sooner throw herself into the deep fat fryer than pay them more money. Agitprop Sebastian is back to join the strike force and picket the scabs – and Jo gets to see her sweetheart in an altogether new light.

The staff are used to Karen calling the tune, but there's dischord in the ranks when she instructs the staff to sing out the customers' orders. Will Debbie and Derek ever make sweet music again, or will her hot date with good-looking Terry hit the right note?

A battle of wits is in danger of escalating into an all-out war when TJ challenges Ivor Willis, the manager of Blimpy's, to a friendly trivia quiz. With secret weapon Lily up their sleeve, the Spatz team is confident of blasting the Blimpettes clean out of the water – until Lily's grandmother falls ill and she has to go away for the week. Meanwhile, Jo's part-time jobs threaten to knock the stuffing out of her.

TJ gets promoted. It seems like great news, but the downside is he's got to return to Canada (that's somewhere just north of the USA). For Karen this is the upside; that is, until TJ's replacement arrives, in the shape of Melvin Frapelli, slobbish and conniving nephew of the Managing Director. Even Karen's got to admit that things were better before. But how to unseat golden boy Frapelli and reinstate Thomas Jefferson Strickland? That is the question. And it’s a sticky one

Freddy joins the Spatz team as they prepare to welcome football star, Gary Lineker - but is Dexter really the friend of the stars he claims he is?

Karen rashly tells her mother that she is engaged to TJ, and the staff get to grips with Spatz's new weapon in the fast-food war - a delivery bike.

Karen calls in an expert to help improve efficiency levels, and Freddy frets about her relationship with boyfriend, Dave.

Karen has her sights set on marriage, and the other staff have their eyes on a cash prize.

TJ's girlfriend, Julie, fills in at the restaurant when Vince goes AWOL, and the staff deal with the annoyance of a faulty fire alarm.

Four doughnuts are missing - and it's not long before the Spatz staff start disappearing too, as an armed man begins taking hostages.

Debbie has finally agreed to marry her boyfriend, Derek, and Vince can see the money-making potential if he is given permission to organise the reception.

TJ is in trouble with Karen when he allows a talent contest to be held in Spatz.

The staff come to the conclusion the restaurant is haunted, while TJ and Karen prepare for the annual Spatz costume ball.

An important food critic is coming to review the Spatz menu, and a young boy has become separated from his parents.

Karen has lost her contact lens, the bank manager has lost his marbles, and Freddy has managed to lose £3,000 - twice.

A Russian delegation comes to visit Spatz, and Vince goes into the black-market perfume business.

Louis Frapelli has gambled away the London branch of Spatz, and it now belongs to bitter rival, Roland Blimpy. The staff must find a way to win it back.

Dexter's new job isn't what he thought it was, and Vince's wind-up hamburger toy venture winds him up in trouble.

Freddy becomes a crucial witness to a serious burglary, and Karen wants to tap into the lucrative American tourism market.

Rivalry between Spatz and Blimpy's raises its ugly head again, when TJ and Willis agree to hold a ballroom dancing competition.

The local mafia put the squeeze on the Spatz management, and while TJ wants to take a stand, Karen is all for giving the mobsters what they want.

Karen's mean-spiritedness backfires when an old woman puts a curse on her, and the rest of the staff prepare for a visit from Lenny the Lion.

Debbie's boyfriend Derek thinks she's seeing another man, and so takes a job as a security guard so he can watch her. Meanwhile, the rest of the staff take to assembling Christmas crackers for a bit of extra cash.

Vince is in love, the buskers are in trouble, and TJ and Karen are under the mistletoe.
