A Paris-based doctor tries to spread the gospel of Natural Childbirth. Working in a cloistered rural community, Gabin runs up against the stone walls of fear and prejudice. His theories are proven sound when unwed mother Nicole Courcel gives birth within Gabin's methodology. The childbirth sequence is filmed straight-on with a delicate combination of taste and frankness. Nonetheless, the lurid ad campaign of Cas Du Dr. Laurent sensationalized this sequence all out of proportion.

1920, in a small village in Provence. Monsieur Pascal, a young schoolteacher, is faced with a lack of interest from his pupils. He decides to radically change the methods employed by his predecessor. He listens to the children, draws inspiration from their discoveries and takes them out into nature. The pupils will rediscover the pleasure of learning, and he will rediscover the pleasure of teaching. But some parents and notables don't take kindly to this little revolution.
