Erotic movie set in the elisha fields and around the most famous tower in France

Ghislain and his sister Aurore will receive a large inheritance from their recently deceased uncle Edouard only if they can prove their moral rectitude. But the nephew has a mistress, and the niece is a bit of a nymphomaniac. The behavior of the chauffeur, with the maid, tempts their employers into further indiscretions.

Simon and Babeth are seemingly happy couple, but she is not very interested in sex, while he is the opposite. He has sex with his secretary, his older downstairs neighbor, and friend Victoria, as well as other mistresses. But Babeth becomes suspicious and follows him to a hotel where he books a room to make love to one of his mistresses.

The mansion that a young couple inherits has been, they find, a center for sophisticated depravity. They get immersed in voyeurism and hedonistic love triangles with their willing servants. Eventually the entire household, including the guests at a formal dinner party, get caught up in the antics.
