Paris 1930. Paul has only ever had one and the same horizon: the high walls of the orphanage, an austere building in the Parisian working class suburbs. Entrusted to a joyful country woman, Célestine, and her husband, Borel, the rather stiff gamekeeper of a vast estate in Sologne, the city child, recalcitrant and stubborn, arrives in a mysterious and disturbing world, that of a sovereign and wild region. The huge forest, misty ponds, heaths, and fields all belong to the Count de la Fresnaye, an elderly taciturn man who lives alone in his manor.
