Thrown together by chance, a group of people search a city for a kidnapped peace activist. Set in Allied-occupied Germany, it was shot on location in post-World War II Frankfurt-am-Main (with exterior and interior shots of the IG Farben Building and its paternoster elevators) and Berlin. During the opening credits, a full-screen notice reads, "Actual scenes in Frankfurt and Berlin were photographed by authorisation of the United States Army of Occupation, the British Army of Occupation, the Soviet Army of Occupation."
