Family Jewels (1975)

After the death of a provincial bourgeois, George Laffite, all his close relatives are gathered in his huge mansion to mourn him and see who gets what from his estate; an attractive widow, Hélène, aged thirty-five, Antoinea, moronic son, Victoire, daughter at religious boarding school and the reactionary grandfather, Edmond. Suddenly freed from paternal supervision, the family members plunge into unrestrained sexuality with a rutting driver and an equally willing maid, eliminating all the differences in status. Greed, lust, love and class conflict between the family and their payed servants create a real mess rather quickly.
