Interdit au public.

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.
