In this French satire, a femme fatale captures the soul of every man she encounters. The story really begins as a hapless fellow picks her up at a church and ends up taking her back to his apartment. He does this out of kindness, not out of sexual desire. He soon falls in love with her and so does his roommate who immediately jilts his fiance. The two rivals eventually catch on to her games, throw her out and begin living their regular lives.
