Flesh and Fire (1985)

Directed by Gérard Kikoïne

American Raphael talks his colleague at the Parisian University into spending his summer at the family's country mansion. But once there Raphael seduces and plays the sisters and mother against each other - until everyone is revealed at their very worst. As it turns out - that was Raphael's intention all along - because his own torrid past is deeply rooted in their family's dirty history.
