In this true-life Cold War spy thriller, unassuming British businessman Greville Wynne (Benedict Cumberbatch) becomes entangled in one of the greatest international conflicts in history. Recruited by MI6 and a CIA operative (Rachel Brosnahan), Wynne forms a covert partnership with Soviet officer Oleg Penkovsky (Merab Ninidze), and both men risk everything in a danger-fraught race against time to provide the intelligence needed to prevent nuclear confrontation and end the Cuban Missile Crisis.
