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.
