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.
