A reformed London gangster called Terry Molloy arrives in Aidensfield to start a new life and comes to the attention of the police when he saves Rob from a beating at the hands of a gang of reckless hooligans. Miller wastes no time in putting him in the frame when a safe is blown in Ashfordly, much to Rob's dismay. Worse still, Younger accidentally reveals Molloy's whereabouts to a snooping journalist, and the news soon reaches Molloy's former underworld associates. Meanwhile, Aunt Peggy causes a salmonella outbreak when her chicken-feed racket backfires, whilst Helen and Rob have embarked on an full-blown affair, and Ventress is concerned when his wife falls ill.
