Synopsis

Paul is actually quite happy with his life. He is a successful doctor, has a pubescent daughter and is in a seemingly happy marriage with the attractive Julia. But as in many marriages, the passion has faded over time. It is quite different with her best friends Vanessa and Marc, with whom there is obviously still a spark. One evening, over a nice dinner in a drunken mood, Vanessa tells Julia a little secret: she and Marc have been meeting up with like-minded couples for a few months to swap partners. Vanessa raves to Julia about how passionate her relationship with Marc has been since then. Julia is quickly hooked. For her, her marriage is nowhere near as good as it is for Paul. When Julia tells him about the secret, Paul can't believe it at first. It's not for him. But Julia puts her husband under so much pressure that he finally hesitantly agrees to a "trial" with Marc and Vanessa.
