Babette Goes to War (1959)

Beautiful housekeeper Babette travels to England after the Nazis invade France. There, British intelligence devise a plan for Babette to sneak back home, where she could use her feminine charm on key Nazi officer Schulz, gleaning valuable information for England. However, Babette, although willing and spirited, is naïve and untrained, making her less than ideal for matters of national security.
