Ils se marièrent et eurent beaucoup d'enfants

Vincent and Gabrielle (Yvan Attal and Charlotte Gainsbourg) seem to have an idyllic life. However, Vincent has been cheating on Gabrielle, and she knows it. The problem is not that Vincent doesn't love her anymore or that he no longer lusts for her, but that he does. It's just that he happens to love his mistress as well... Meanwhile Gabrielle (unbeknownst to Vincent) embarks on a fling with a mysterious man she meets in a record store (Johnny Depp). Vincent's friend Georges, on the other hand, has always been faithful to his wife, but seems to have tired of her and their son. What he thinks he wants, but doesn't have the courage to go out and get, is the kind of life Fred, a playboy buddy of his, has created for himself. That is to say; no commitments and a different girlfriend seemingly every night. It is a life that Fred though is tiring of, and turning his attention to the pursuit of monogamy.
