Tonight We Raid Calais (1943)

British Intelligence dispatches commando Geoffrey Carter on a one-man raid to destroy a munitions plant that manufactures bombs in German-occupied France. He enlists the aid of a patriotic farmer, M. Bonnard, who lives near the plant, over the objections of his daughter Odette Bonnard, who believes that the British are responsible for the fall of France. Her attitude softens toward Carter, who is living with the family as posing as a son, but Odette cannot bring herself to aid in Carter's plan because of her fear of reprisals against her family. She turns informer and the Germans capture Carter.
