While on his way to Tangier to purchase a microfilm containing important war secrets, foreign spy Eric Augustine (Bob Hope) is wounded by the authorities and hospitalized. Burlesque comedian Peanuts White (also, Bob Hope); a dead ringer for Augustine is recruited by the government to take over Augustine's mission. He's briefed in the role of the suave and romantic Augustine, dressed to look exactly like him and is thrust into the world of espionage and inter-national intrigue. In Tangiers, he meets Lily Dalbray (Hedy Lamarr), Augustine's sweetheart, a beautiful spy working with Karl Brubaker (Francis L. Sullivan) mastermind of the spy ring. All of Bob Hope's "My Favorite" films (My Favorite Blonde, My Favorite Brunette, My Favorite Spy) were parodies of classic genre films.
