What's in a Name?

Vincent, a successful man in his forties, is about to become a father for the first time. He is invited to dinner with his sister Élisabeth and her husband Pierre, where he meets Claude, a childhood friend. As they wait for Vincent's young and permanently late wife Anna to arrive, the others ply him good-naturedly with questions about his future fatherhood. But when Vincent is asked if he already chosen a name for the baby, his answer sows uproar among the assembled company.
