Stefan Radetzky, a Polish pilot and famous concert pianist, is hospitalised in England from injuries sustained while in combat, and having lost his memory. As Radetzky plays the piano in a trance-like state, the story moves back in time to war-torn Warsaw. During an air-raid, Radetzky meets American journalist Carole, and there is a mutual attraction. Following the fall of Poland, Radetzky and Irish pilot, Mike, escape to Rumania and then on to America. Radetzky continues his musical career in America and meets up again with Carole.

Suave soldier of fortune Simon Templer gets mixed up with a gang of counterfeiters who've murdered and robbed an European count of 1,000,000 pounds. He is aided reluctantly by Scotland Yard inspector Teal, who's convinced that Templar himself pulled off the heist, and less reluctantly by light-fingered Dugan and dizzy socialite Penny Parker.
