Tony Stamp joins a dating agency for professional people, telling them he is an antiques dealer, and as he is living in the section house, gives them Polly Page's address. A CID operation involving forged banknotes goes wrong, and Sgt. Gilmore tells Stamp and Hayward off when they pursue and arrest an armed suspect without backup. When DC Webb and DC Spears investigate a series of robberies, they discover a link to Tony's dating agency, and that Tony's date Lisa invites men to stay at her flat and then arranges for their house to be burgled. CID set up surveillance outside Page's house, and catch the thieves, and Stamp must sadly arrest Lisa.
