弗朗索瓦和乔尔是恋人，他们在性爱种获得了极大的快乐。但弗朗索瓦是一名摄影师，他将工作排在首位。一天晚上，他们被工作电话打断，弗朗索瓦带着相机和三件衬衫匆匆离开时，乔尔迫不及待地把这些衬衫都弄脏了，然后才感到性满足。因此，她出去寻找，并发现，与男性和女性一样的一些联络。在她的一次出游中，她碰巧看到弗朗索瓦和一个男人有染。看来她并没有拒绝再次加入他的想法——以三重奏的形式。

François and Joelle are lovers, and take great pleasure in their sexual embraces. But François is a cameraman that puts his work at a higher priority. One night, when they are interrupted by a phone call from his work, and leaves in a hurry with his camera and three shirts, Joelle can't wait all those shirts to be dirty before she is sexually satiated. Therefore, she goes out searching, and finding, a number of liaisons with men and women alike. On one of her outings, she happens to see François having an affair with a man. It seems that she doesn't reject the idea of joining with him again - in a menage-a-trois.
