The young Jeanne (Brigitte Bardot) takes pleasure in seducing and then destroying men. The successful Pierre (Maurice Ronet) is hopelessly infatuated with her, as is the macho Louis (Robert Hossein). While Pierre turns to the bottle to drown his sorrows in alcohol, Louis is humiliated by Jeanne's lustful enticement of his wife Clara (Jane Birkin). Jeanne's third lover, a guitarist, is even willing to kill himself for a night with her. After his suicide, she confesses her misdeeds to her cousin Paul, a priest (Mathieu Carrière) – with the result that he, too, is aroused. Then she suddenly sees Pierre again, and a new catastrophe looms... Sex symbol Brigitte Bardot turns the tables: As the female reincarnation of the great seducer Don Juan, she shows how easily men fall for her charms.
