In a small French town during the Occupation, Barny is a young, wayward, sexually frustrated widow, living with her little girl. She is also a communist militant who long ago decided that the easiest way was the best. One day she enters a church, randomly chooses a priest and starts criticizing the religion. But the priest is Leon Morin, who is young, handsome, clever and altruistic. He believes that any sin can be expunged by a good dose of faith, and does not offer her the reaction she was expecting. She is disturbed. She starts frequenting Morin, impressed by his moral strength, while he makes it his mission to steer her onto the right path.
