IMDb:
Perci Trachtenberg, widely regarded as the world's greatest living mathematician, meets Venkat, a reclusive math genius from India, at a high rolling casino in London. Venkat tells Perci about an equation that could not only change the dialogue on mathematics forever, but one that has already left an indelible impression of guilt - for many painful reasons - on Venkat's life. Ben Kingsley, who starred in Sexy Beast, plays Perci in this film.
