Six British teenagers spend a summer training for the International Mathematical Olympiad, the annual contest that pits national teams of gifted young mathematicians against brutally hard proof-based problems. The film follows the UK squad through selection camps and into the 2006 competition, held in Slovenia, spending most of its time on Daniel Lightwing, a Newcastle student whose talent for numbers sits alongside real difficulty reading social situations. Coaches and parents talk candidly about what it costs to raise a prodigy, and the camera catches the awkward small talk, nervous tics, and flashes of humor that come with assembling a team of teenagers who think faster in equations than in conversation. Training footage shows the group working through olympiad-level problems on whiteboards late into the night, while interviews trace how each competitor ended up here. The documentary later became the basis for the drama X+Y, but this version sticks to the real students and the real scoreboard.
