Four men, all career criminals, are charged over the fatal shooting of a policeman and the serious wounding of another, during an armed hold up. When they walk free because of a legal technicality, the city reels in shock.

Having attacked Kirsty outside of court months earlier [ep 3], Rhonda Hennessey is now on trial herself facing a charge of attempting to pervert the course of justice for threatening Kirsty to keep her from testifying against Mal and Steve. Despite a last minute attempt by the defence to keep Kirsty from testifying due to her delicate condition (she is now six months pregnant with Steve's child), Kirsty takes to the witness stand for the prosecution but in recounting the incident, she is evasive and downplays Rhonda's threats.

Peter Faithful’s evidence against Steve Hennessey and Darren Mack proves to be extremely incriminating. However, it is up to Michael Kidd to discredit the experienced detective. He accuses Peter of conducting a vendetta against the Hennessey family, improper police practices, carrying out illegal searches on the Hennessey home, and planting drugs.

Rhonda Hennessey's de facto husband, Darren Mack, attempts to run an extortion racket inside prison, but his first victim does not frighten easily and turns Darren in. The situation is exacerbated when Michael Kidd sees this as an opportunity to further discredit Peter Faithfull and his team.

Darren Mack is on trial for extortion. Michael Kidd is doing his best to prevent Darren's sentence from being increased, only to be sacked by the Hennessey in-law. However, unlike Mal, Darren's attempts to represent himself begins to verge on the ludicrous.
