At Your Service(2005)

Young Hervé has just spent the night boozing and having sex at a party. On his way back home, he has a car accident and is transported unconscious to a strange house where lives an even stranger family. The lord of the manor, a man with huge sexual desires is also an ardent voyeur. His wife and daughters-in-law are more than happy to play along the old man's authoritarian tendencies and regularly stage a very special play based on their own brand of erotic depravity.
