It is Constable Susie Raynor's first day in Mt Thomas and as she is being given the guided tour, she recognises a released paedophile who has moved into a house opposite a primary school. Ben is appalled, and makes sure he warns the community, but the man Donald Heinz asserts both his innocence and his civil rights, causing much community division and leading Tom to question his decision to appoint Ben as Acting Sergeant. Then a young girl goes missing and the man is accused of abducting her.
