Narrated by actor Glenn Ford, this brilliantly produced documentary made by CBS is of a mock evacuation of Portland, Oregon during a nuclear attack. The film shows how a typical American city can evacuate its citizens in a safe and timely manner when under threat of an atomic bomb assault. A wonderful piece of the history of the atomic bomb, the film utilizes expert timing and narration to elicit a feeling of dread and suspense that would accompany such a disaster. But organization and readiness are stressed, allowing the emergency to be coped with. This is a great civil defense film and one of the best movies in Portland ever shot that details the evacuation routes and emergency procedures necessary to keep a city safe against the threat of nuclear war.
