Pierre-Joseph is 16 years old when he joins a training center to become a gardener. There he meets Françoise Brown, the director, Alberto, his botany teacher, and Adrien, his employer, all of whom are decisive in his apprenticeship and the discovery of his sexuality. 40 years later, Kutta, Françoise Brown's adopted child, whom he has always heard about, arrives. But Kutta, who has become the owner of the strange castle of Antiville, seems to be looking for something more than a simple gardener.
