Adam, 15, has a bizarre condition—his body changes based on the mockery he gets. The summer that his grandma dies, he must grow up fast. He maintains the Brousseau mansion while snobby Kevin is away, and mows Mr. Bibeau’s lawn post-surgery. Between his deforming body, summer jobs, tension with his sister Karine, a crush on Jeanne, bullies, clumsiness, and his friend Timothée, Adam faces the chaotic beauty of teen life.
