Five years of psychotherapy have failed to alleviate Damien's anxiety about life. Dr. Beranger can't stand him anymore. So he challenges him with a therapeutic challenge: find the woman of his dreams. And against all odds, Damien succeeds. Three months later, his fiancée Alice invites him to her family home to meet her parents, who are having a big party for their 30th anniversary. As soon as he arrives, nothing goes right. But the worst thing is that Alice's father turns out to be none other than Dr. Beranger himself.
