One rainy night, Antoine gets dropped off at his grandparents' remote house in the middle of the woods. He's stuck between a doting grandmother and a grandfather openly hostile to his presence, and time crawls by while he waits to hear from his parents. When Antoine ventures out with his grandfather to forage for mushrooms, intergenerational conflict and mysterious forces of nature culminate in a fearsome hunt through the forest that will resolve their differences once and for all.
