Les gens qui s'aiment (1999)

Two middle-aged lovers have been involved on and off for over twenty years. Angie's younger daughter Winnie connects with Laurent, who has strongly bonded with the Richard Berry character. From the outset, the younger couple is as erratic as the older couple in their love affair. Will these two relationships continue chronically? What will it take to achieve a happy medium for a stable, long-lasting relationship?
