Spies Beneath Berlin

This film tells the extraordinary true story of a top-secret British-American mission to build a spy tunnel beneath Cold War Berlin.

In 1954, MI6 and the CIA set out to tap Red Army communications and gain warning of a possible Soviet attack. They had to evade East German and Soviet troops, tunnel through unstable ground, and conceal a vast engineering project in one of the world’s most closely watched cities.

Using first-hand accounts and fresh scientific and historical analysis, the film reveals the full story of this remarkable operation.
