In a French village, Manou is an Italian logger, virile, with a broad laugh. He can't say no to women's sexual invitations, and jealous villagers blame him for recent fires and a flood. He is innocent; the culprit is "Mademoiselle," town schoolmarm, a recent arrival admired by all, but sexually repressed and obsessed with Manou. She sets the first fire accidentally and throbs watching a shirtless Manou perform heroics. Subsequent catastrophes are no accident and express her mad passion for him. Also, after befriending Manou's son, she turns on the lad, making him miserable and raising his suspicions. Her designs, Manou's frank innocence, and the town's xenophobia mix explosively.
