A true Cold War espionage thriller set around the ultra-secret Berlin Tunnel - where British officer George Blake must run a high-stakes double cross to maintain his cover. The ultra-secret "Berlin Tunnel" was dug in the mid-1950s from the American sector in southwest Berlin and ran nearly a quarter-mile into the Soviet sector, allowing the CIA and the British Secret Intelligence Service (SIS) to tap into critical KGB and Soviet military underground telecommunication lines. George Blake, a trusted officer working in a highly sensitive job with SIS, was privy to every aspect of the plan.
