In 1960, Oleg Penkovsky, a high ranking Soviet official and GRU intelligence officer with access to top secret nuclear information, is disillusioned with Khrushchev's leadership in light of the growing threat of a nuclear war with the United States. He reaches out to the CIA and offers to provide information that could help de-escalate the situation. The CIA and MI6 decide that it would be better not to use an officer and instead have an ordinary businessman act as an intermediary.
