It's a love triangle with a twist: Dan (Olivier Sitruk), an inveterate womanizer and commitment-phobe, is finally ready to tie the knot with Camille (Julie Gayet). His best friend, Laurent (Arnaud Giovaninetti), is a gay activist with a secret crush on Dan. Laurent tries everything he can think of to derail the impending nuptials, but as Dan's best man, he must choose whether to support his friend or be true to his own heart's desire.
