A posh mountain resort contrasts starkly with a gloomy valley filled with cheap housing, bleak parking lots and empty stretches of land. Twelve-year-old Simon lives in the valley with his sister, Louise. In winter, he trudges up the mountain to steal equipment from the skiers and discovers a yawning gap between their world and his. He sells his plunder to earn some money to support his aimless sister, who is out of work. Lost in both an emotional and literal no-man’s-land, the boy tries buying the love of the people around him. Yet his constant treks up and down the mountain leave him lonely, distraught and old before his time. In her second feature, Meier takes an un- compromising look at broken families living on the fringes and expands on themes covered in Home, her first film. Sister offers razor-sharp camera work by Agnès Godard whose precise shots and framing reveal the physicality and cruelty of this world. Kacey Mottet Klein and Léa Seydoux deliver gut-wrenching performances as siblings whose relationship is founded on lies and deceit.
