In the shadow of the Cold War, the British Royal Air Force and the United States Air Force transformed rural airfields into high-security bastions of nuclear deterrence. Through the lens of RAF Bentwaters and Orford Ness, this documentary explores the intense, often secret, efforts to maintain a constant state of readiness against the threat of nuclear conflict. From the development of jet-powered aircraft to the construction of hardened bomb shelters and nerve centers, the film reveals the chilling reality of a world living under the constant shadow of mutually assured destruction.
