Synopsis: As the British military prepares to invade Sicily during World War II, intelligence agent Ewen Montagu hatches a cunning plan to fool Germany into believing the Allies' true target is Greece. Concocting a fictitious British officer named Maj. William Martin, Montagu gathers false top-secret documents and personal letters to plant upon a corpse that will wash ashore in Spain. But the investigations of a German undercover agent could potentially expose the fraud.
