At an international boarding school, an unassuming, yet rigorous, Miss Novak (Mia Wasikowska) joins the teaching staff to instruct a new class on "conscious eating."
Her impressionable teenage students each have their own reasons for joining the class - to improve fitness, reduce their carbon footprint, or get extra credit. Although early lectures focus on mindful consumption, Miss Novak's discussions soon become increasingly disordered and extreme. As a few devoted pupils fall deep under her cult-like tutelage, they are given a new, even more sinister goal to aspire to - joining the ominous "Club Zero”. An often disturbing but always engaging film.
