Cold War's Deadliest Secret: The KGB Defector

On May 18, 1985, a high-ranking KGB Colonel landed in Moscow. He was the head of the London Rezidentura and MI6's most valuable spy.

This is the incredible true story of Oleg Gordievsky, the Cold War's most important double agent. For 12 years, he passed top-secret Soviet files to the West, helping to prevent a nuclear war.
