Every year, teenagers from more than ninety countries compete at the International Mathematical Olympiad, and this film follows the UK team as they train for a shot at gold. The central figure is Daniel Lightwing, a working-class student whose ability with numbers offers him a path out of his circumstances but who struggles with the social side of a team built almost entirely from boys who see the world in similar, singular ways. Cameras follow the squad through grueling practice papers, a training camp, and the tension of the competition itself, where a handful of extra marks separates a medal from nothing. Coaches and former Olympiad competitors describe what it takes to hold six problems in your head at once, and the film does not shy from the awkwardness and isolation that can come with this kind of talent. It is as much a portrait of adolescence under pressure as it is a math competition film, built around Lightwing's specific story rather than abstract praise of genius.
