Vincent (Patrick Bruel), a successful forty-something, is about to become a father for the first time. He is invited for dinner at the quaint apartment of his sister, ?lisabeth (Val?rie Benguigui), and brother-in-law, Pierre (Charles Berling) where he catches up with his childhood friend, Claude (Guillaume de Tonqu?dec). Whilst waiting for Anna (Judith El Zein), his younger spouse who is always running late, his cohorts gleefully bombard him with questions on his fast approaching fatherhood... But when his hosts ask Vincent whatname he has chosen for his future offspring, his response plunges the family into chaos.
