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.

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.

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

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.
