Lovely Sundays (1974)

The psychological tensions which are driving four bourgeois couples apart are blithely ignored, as they attempt to party through them, all the while discussing politics, flirting, and drinking heavily. One of the couples includes the daughter of an older couple, together with her first serious lover. An idyllic pair at first, their problems multiply and they begin to resemble their more dejected and dissipated elders. The movie is based on the successful play by Marcel Dube.
