Fail-Safe is a 1964 Cold War thriller directed by Sidney Lumet. An unidentified object heading toward the United States triggers a defense alert. Following a standard defense protocol, the Air Force sends a squadron of SAC bombers to respond to the threat. Expecting a stand-down order, squadron commander Jack Grady (Edward Binns) is shocked when he receives a confirmation code to conduct a thermonuclear attack on Moscow. When he tries to confirm the order, he finds that his communications are blocked by Soviet scamblers. Meanwhile, back in the United States, military leaders have converged on a bunker deep below Washington D.C. to discuss how to deal with the computer malfunction that has led to the accidental deployment of the bombers. As the world nears Armageddon, the President (Henry Fonda), General Black (Dan O'Herlihy), civilian advisor Groeteschele (Walter Mathau) and General Bogan (Frank Overton), fight time and each other to stop the unthinkable. As the dilemma unfolds, only one solution remains.
