Nicolas (Sébastien Boivin) lives a rather harmonious relationship with Valérie (Natasha M. Leroux), punctuated visits to a swinger club of the city. During a supper with two couples of friends, the audacious Valerie reveals her desire to introduce them to this sexual practice. The idea pleases Charles (Erwin Weche) and Luc (Sylvain Latendresse), but much less to their respective spouses, Veronique (Kina Beauchemin and Lisa (Diana Lewis). Nevertheless, the six friends agree to go to the club, where Veronique, who was already secretly unfaithful to Charles, takes a liking to experience. But Charles could not bear to see her in the arms of another man. On the other hand, the shy and submissive Lisa takes no pleasure in sharing, contrary to the scornful Luc, who finds there a way to satisfy his voyeur fantasies.
