Daly and Rawton go undercover as the landlord and landlady of a local pub while investigating a gang who have operating a protection racket on the local pubs and clubs. Daly befriends a small-time petty crook who offers him some dodgy gear on the sly. Meanwhile, Garfield is in court for the case of a shoplifter who assaulted him during the arrest. When the woman is cleared of the assault, Garfield is positive that one particular magistrate was responsible for the dismissal. When Conway invites her to spend a day on patrol with Garfield and McCann, Garfield loses his cool. As Daly and Rawton think they have lost their prime suspect, the crook who Daly has befriended manages to salvage a deal.
