There is a new bobby in Aidensfield. Steve Crane will replace PC Bradley, who has been transferred to CID. Crane is not the only newcomer in the village. Dr. Liz Merrick moves in at the surgery as the new GP in Aidensfield. She is concerned about the loss of patients since her predecessor died, but Vernon Scripps offers to deliver a letter from her to every potential patient in the village. Two neighbouring farms have been broken into, but the owners Jack Farrow and Walter Rawlins say the break-ins are mere trifles and not worth any police attention. PC Crane does not agree and suspects they cover something up. Gerald Dunphy is wanted for armed robbery and Mike's first case as a detective constable is to keep an eye on his girlfriend in case he shows up.
