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.
