A new Nazi governor of Paris wants to intimidate the French so he gets murdering lunatics released from asylums and has them disguised as the gargoyles from the top of Notre Dame. They accompany the German patrols of the streets to assault the French, and when the citizens beg the guards to intervene, the Germans laugh and pretend not to see the gargoyles. They even dab the claws of the stone gargoyles from the rooftop with human blood to enhance the illusion. The French underground send for help from Cap and Bucky and when they arrive they battle the governor at Notre Dame. The evil doer falls to his death from the rooftop and Cap gets a goodbye kiss from a grateful Frenchman.
