Twelve-year old Anaïs is fat. Her older sister, Eléna, is a teenage beauty. While on vacation with her parents, Anaïs tags along behind Eléna, exploring the dreary seaside town. Eléna meets Fernando, an Italian law student, who seduces her with promises of love, as the ever-watchful Anaïs bears witness to the corruption of her sister’s innocence. Precise and uncompromising, Fat Girl (À Ma soeur!) is a bold dissection of sibling rivalry and female adolescent sexuality from one of contemporary cinema’s most controversial directors.
