Synopsis: Countdown To Zero traces the history of the atomic bomb from its origins to the present state of global affairs: nine nations possessing nuclear weapons capabilities with others racing to join them, with the world held in a delicate balance that could be shattered by an act of terrorism, failed diplomacy, or a simple accident. The film makes a compelling case for worldwide nuclear disarmament, an issue more topical than ever with the Obama administration working to revive this goal today.
