Relative to Breillat's other movies, 2001's Fat Girl is fairly tame until its problematic conclusion. Documenting the misadventures of fifteen-year-old Elena (Roxane Mesquida) and her younger sister Anaïs (Reboux) while on a family vacation, the movie highlights the disparity between the girls' attitudes toward sex despite their shared virginity. The older sister, who is slender and conventionally attractive, is interested in entertaining men's spirited advances and harbors a romantic naïveté when embarking on a dalliance with Italian law student Fernando (Libero De Rienzo) that she mistakes as more than a fling. Though only twelve, Anaïs, whose beauty is often ignored because of her size, is far more cynical. She wants her first time to be with someone she does not love and watches in horror as her sister gets played, her warnings ignored.
