Unexpected news from Zoe leads Nick to spring a surprise of his own - his resignation from the Victoria Police. In typical Nick style, he refuses to provide a reason for his resignation, hampering Tom's attempts to talk sense into him. But as the Heelers try to discover the real motives for Nick's strange behaviour an angry dispute over a parking ticket leads to the arrest of a chook farmer, the death of some chickens and the disappearance of a parking inspector. The chook farmer becomes the prime suspect, but investigations unearth a secret life and plenty of people with good reason to hate the officious inspector. When a wedding celebrant visits and Nick is sprung baking a wedding cake, the Heelers finally put two and two together to discover the truth.

Tess and Jonesy investigate a domestic disturbance and Tess is reacquainted with Hayley, a troubled young girl from her past. An unpopular neighbour's portrait is discovered riddled with bullets and he is adamant that Hayley is responsible but Tess defends her. An elderly woman's dog is found shot dead and PJ discovers that the bullets from both crimes match. When the weapon is found, Hayley is implicated. Tess' faith in Hayley's innocence leads them to the truth but places Hayley's future in jeopardy. Will Tess challenge the stability of her own world for the sake of Hayley's?
