Clifton Webb, Robert Flemyng and Gloria Grahame star in this classic drama set during the Second World War, adapted from the book by Ewen Montagu which is based on real events. In order to deceive the Germans into thinking that the Allied forces are preparing to invade Greece, and not Sicily as planned, intelligence officers Lieutenant Commander Ewen Montagu (Webb) and Lieutenant George Acres (Flemyng) are tasked with a complex mission - they must find and dispatch a dead body under a fake identity of a British major into the sea, along with plans for the bogus invasion, to be discovered by the Nazis. Will the operation be a success or will the Germans discover the truth?
