Backstage at a Paris theater, a famous, exasperatingly fatuous playwright learns that the actress who was to play the lead in his play is expecting a child. No great actress is available to take on the role. Except the famous actress Gabrielle Tristan, to whom he was married for ten years and to whom he no longer speaks. But their love of theater and their playfulness outweigh all their grudges, and Gabrielle takes on her ex-husband's play.

Dans les coulisses d'un théâtre parisien, un célèbre auteur dramatique, exaspérant de fatuité, apprend que la comédienne qui devait tenir le rôle principal de sa pièce attend un enfant. Aucune grande actrice n' est libre pour reprendre ce rôle. Sauf... La célèbre comédienne Gabrielle Tristan avec qui il a été marié pendant dix ans et à qui il n'adresse plus la parole. L'amour du théâtre et l'esprit cabotin seront plus forts que toutes leurs rancunes et Gabrielle jouera la pièce de son ex mari.
