Zoé is determined to be the sole focus of Martin's attention, but Martin has a long-time lover, Elke, who comes in and out of their lives as she pleases. Zoé gives Martin an ultimatum to choose between the two women, and Martin gives her a game. Elke will give Martin and Zoé a sexual challenge, and if they succeed, they win that round. Martin will then give Elke a challenge. The first to fail a challenge loses the game. If Elke loses, then she is out of Martin's life. If Zoé loses, then she must submit to Elke and leave Martin and Paris. Each erotic challenge gets more dangerous and perverted. Who will win in the House of Games?
