X + Y Synopsis

A young maths genius has his logic thwarted by the one thing he can’t make sense of - love.

Teenage maths prodigy Nathan (Asa Butterfield) struggles with people, not least his mother, Julie (Sally Hawkins), but finds comfort in numbers. Mentored by unconventional and anarchic teacher Mr Humphreys (Rafe Spall), Nathan’s talents win him a place representing GB at the International Mathematics Olympiad.

When the team go to train in Taiwan, headed up by squad leader Richard (Eddie Marsan), Nathan is faced with unexpected challenges - not least his new and unfamiliar feelings for his Chinese counterpart, the beautiful Zhang Mei (Jo Yang). 

From suburban England to bustling Taipei and back again, this original and heartwarming film tracks the funny, complex relationship Nathan has with his mentor who ends up learning more from Nathan than he could ever teach him. Ultimately this is Nathan’s journey to embrace the irrational nature of love.
