Anne-Marie lives an easy life with Gilbert, a rich plastic surgeon: a beautiful house, a doggy, a cleaning lady, expensive furniture, the lot. Not so easy in fact when she thinks twice. She does not get on with her husband any longer. She gets on his nerves and he does not attract her any longer. She feels good only when she jogs on the beach and ... when she is the arms of her lover, Leo. One day, Gilbert gets killed in a car accident. Good news, since she will be able to live with Leo. The trouble is her well-meaning family settle at her villa with a view to supporting the "poor widow" morally. Anne-Marie just cannot admit she is not distressed at all, especially to her son Christophe. She is now even more of a prisoner than when Gilbert was alive...
