A young math genius sees logic thwarted by one truly baffling equation: love.
Teenage math prodigy Nathan (Asa Butterfield) struggles when it comes to building relationships with other people, not least with his mother, Julie (Sally Hawkins).
In a world difficult to comprehend, he finds comfort in numbers. And when Nathan is taken under the wing of an unconventional and anarchic teacher, Mr. Humphreys (Rafe Spall), the pair forge an unusual friendship.
Eventually, Nathan's talents win him a place on the UK National team at the International Mathematics Olympiad (IMO) and the team travel to a training camp in Taiwan, under the supervision of squad leader Richard (Eddie Marsan).
In unfamiliar surroundings, Nathan is confronted by a series of unexpected challenges, not least the unfamiliar feelings he begins to experience for his Chinese counterpart, the beautiful Zhang Mei (Jo Yang), feelings that develop when the young mathematicians return to England for the IMO, held at Trinity College, Cambridge.
From suburban England to bustling Taipei and back again, this original and heart-warming film tracks the funny and complex relationships that Nathan builds, as he is confronted by the irrational nature of love.
