Petros Papachristos devotes his life to proving one of the greatest mathematical challenges of all time: Goldbach's Conjecture. In a host of countries, spanning various wars, and against a tableau of famous historical figures - among them G.H. Hardy, the self-taught Indian genius Srinivasa Ramanujan, and a young Kurt Godel - Petros works furiously to prove the notoriously difficult conjecture. Suddenly for no apparent reason, he disappears into the Greek countryside.To his nephew, he is know as the solitary, eccentric Uncle Petros, but when the young man finds out that his uncle is an esteemed professor of mathematics, he searches out his uncle's hidden past. Through an adversarial friendship based on chess and mathematics, he drives the retired mathematician back into the hunt to prove Goldbach's Conjecture ... but at the cost of the old man's sanity, and perhaps even his life.
