Hervé Montagne, a famous but awfully self-satisfied playwright, is furious when he learns that the actress signed to lead in his latest play will not be able to play the part on account of pregnancy. All the more as no other great actress is available. Well, in fact there IS one, Gabrielle Tristan, a great name of the French stage. The only trouble is that she is Hervé's ex-wife and that they have not been on speaking terms for ten tears.

Bienaimé, a modest postman, in love with Janine, the village postmistress, does not know that he is the illegitimate son of the old Baron de Mondésir. The Baron dies and in happy amazement, Bienaimé finds he is the sole heir to the deceased's estate. But he should be careful, for two crooks, Waldemar and Erika, are after his newly-acquired wealth.

The film tells the story of three presenters on Radio X, an amateur clandestine radio station.
