Lawson is a part of a high speed chase involving a group of carjackers, Kerry is pulled over for drunk driving, and Josh, Grace and Michael are involved in a fatal car accident.

When a group of students are lured into being drug mules, TR races to stop them, as Kerry warns Lawson he risks compromising a federal investigation.

TR is called to a domestic siege on the outskirts of Melbourne where they journey into dense bush to save a young boy.

When Josh is shot, Lawson faces a dilemma in how to neutralise the boy. Meanwhile, Kerry receives the brief for the coronial inquest and must prepare to face the consequences of causing a cyclist’s death.
