What happened during that summer of 1978 is the most incredible sporting story that has never been told… until now. 

After Fischer beat Spassky in the 1972 World Chess Championship, the Soviets plotted to regain this coveted title by supporting Anatoly Karpov – a loyal member of the Communist Party. Fischer refused to defend his title and Karpov was crowned King, but his first title defence was against Viktor Korchnoi – a critic of the Soviet regime and high-profile defector since 1976. As the rivals fight on the chess board, their teams are locked in a war of espionage, parapsychology, coded yoghurts, KGB agents, death threats, and a mystic sect wanted for murder.

2018 marks the 40th anniversary of the World Chess Championships.
