Margaret Ross is an impoverished old woman who lives alone in a seedy apartment and enjoys a rich fantasy life as an heiress. One day she discovers stolen money hidden by her son and believes her fantasy has come true.

This spin-off from The Odd Man (1962) starred William Mervyn as the acerbic Inspector Rose, who, alongside the soft-hearted pensive Det. Sgt. Swift (Keith Barron), are joined by Anthony (John Carson) and Alice Brand (June Toblin), a barrister and his journalist wife, though not for long. By the second season, the Brands and Swift departed, leaving the calm, cold Rose in prime position, supported by newcomers DS Hunter (Anthony Ainley), his girlfriend Claire (Veronica Strong), and her boozy reporter friend Fred Blaine (John Stratton).

During World War I, young Londoner Tom Grattan is sent to live with relatives in rural Yorkshire, where he becomes involved in espionage, sabotage, and other wartime adventures with local friends, facing threats like spies and German POWs.
