Alongside Totoche, Paul will make a school out of life, out of nature's secrets, and learn to clean fish and everything there is to know about game, mushrooms, and plants.
Paul, a boy orphaned during the WWI, comes to the Count of Fresnaye's estate to live with a foster family: Célestine, a maid at the manor, and her husband Borel, the gamekeeper.
Left mostly to himself, and warned against showing up at the castle, because the Count doesn't tolerate children, Paul begins to explore the surrounding wilderness.
The estate is about to pass to the Count's no-good son, a blatant egoist with property development ideas that would ruin the environment.
Filming for the movie began on 19 September 2016 in Sologne, Chambord, Loir-et-Cher, Beaugency and La Ferté-Saint-Cyr and wrapped up on 25 November in the same year.
