Rosie

PC Michael Penrose, nicknamed to his embarrassment Rosie, returns to his native town, the resort of Ravensbay, when he learns that his exotic, pretentious mother Millie is dying. In fact it is a ruse to get him home where Millie and her sister Ida dominate Rosie and hen-pecked uncle Norman. Further woman pressure comes from girlfriend Gillian, anxious to get him to the altar. After a pointless visit from short-sighted informant Merv, Rosie goes to work and, along with slovenly colleague PC Wilmot, is called to a pub disturbance. Here they finally subdue an aggressive drunk after learning that he too is under woman pressure.

Ida and Millie are working in the Oxfam shop,where Millie is pleased to see a better class of customer. Gillian feels sorry for Wilmot,whose wife has left him and is being pursued by WPC Whatmough,so she invites him,along with Rosie,for a meal at her parents' house where Wilmot causes havoc with her father,Bill's, DIY efforts. Worse is to come when myopic copper's nark Merv arrives at the house and Bill innocently asks him to carry a mirror upstairs,resulting in seven years' bad luck all round.

After attending at a burglary Rosie and Wilmot feel that CID treat them as second class citizens. Later they are are called upon to accompany the handsome and sartorially obsessed DC 'Engelbert' Morris to search a yacht in the bay but Wilmot's dressed crab supper and the tide combine to deflate Engelbert's ego. Meanwhile Gillian and WPC Whatmough bemoan their men's lack of interest in marriage.
