Blaketon's car is stolen later is involved in a hit and run accident. Blaketon is acting very secretive and gives a misleading statement about when the car was stolen. Mike thinks that he is guilty but Alf knows otherwise. Blaketon finally confides in Alf and tells him the reason he couldn't say where the car was stolen from was because he was with a married woman at the time. A woman who is married to a senior police officer. Alf sympathises and acts quickly to get the case tied up before CID get involved. Greengrass tries to deal in classic motor bikes but is unsuccessful.

The new Sergeant arrives and that puts Phil, Mike and Alf on their guard. He seems very pedantic over things like uniform, and takes exception to Alf's little habits such as smoking on duty. There is a dance at the village hall, everyone's there and Mike is keen to spend time dancing with Maggie. Unfortunately Sgt Cradock beats him to it! A young girl is at the dance and spends time unsuccessfully trying to get Mike's attention. Later she goes missing and a full search of the woods is mounted. Cradock doesn't have much time for Blaketon's advice, and eventually the girl is found, and her kidnapper arrested.
