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