PJ's quest to solve the mystery of Maggie's murder leads him to the bass guitarist in a recently re-formed rock band. When the muso refuses to give him the answers he wants, PJ decides to apply the pressure by applying for a warrant to search for drugs. Heroin is found, but PJ's plans are soon thwarted because the leader of the band, a faded rock star, takes responsibility for the drugs. Meanwhile, Jack strikes up a friendship with the band's spunky back-up vocalist, who turns out to be the daughter of the band's promoter, Bryce McLeod. PJ investigates Bryce and discovers he was not only named in a top secret drug trafficking inquiry, but was also a close friend of Barry Craig's. Perhaps this is the missing link he is looking for. With PJ applying pressure on Bryce he pulls the plug on the band, bringing about tragic consequences for one of its members. When Jack rescues the daughter from a drug overdose she realises the truth about her father, and decides to help PJ.

PJ's quest to identify Maggie's killer accelerates when a mysterious man is pulled, alive, from a car wreck. He is missing from hospital when PJ and Ben discover a Mt Thomas man has been professionally killed. Is this the hitman who killed Maggie, and has come to finish off PJ, the man who won't let it rest? Against Tom's wishes, PJ offers himself as bait to lure the killer out of hiding. But his every move is predicted. It seems the killer is always one step ahead. But when the killer himself is gunned down in front of PJ, the evidence swings around to implicate an insider, another cop. In an unimaginable act of betrayal PJ finally comes face to face with his nemesis—Maggie's killer and her own brother, Mick Doyle. When the smoke has cleared, PJ and Pat Doyle can finally scatter Maggie's ashes over the land she loved.
