Samuel is a psychoanalyst. All day long, he sees patients who express grievances, particularly rebellious teenagers who despise their parents. This has led him to have a dim view of the idea of becoming a parent. That's when his girlfriend, Mathilde, tells him she is pregnant. Terrified of having a child and being a parent, Samuel sees Mathilde's pregnancy as a nightmare. The advice of Samuel's friend, Marc, a womanizer and a bachelor, does not help Mathilde's anxiety.
