It was the defining moment of the 20th Century - the scientific, technological, military, and political gamble of the first atomic attack. This drama-documentary attempts to do what no other film has done before - to show what it is like to live through a nuclear explosion.
Set in the three weeks from the test explosion in New Mexico to the dropping of the bomb, the action takes viewers into the room where the crucial political decisions are made; on board the Enola Gay; inside the bomb as it explodes; and on the streets of Hiroshima.
For six months, the United States had made use of intense strategic fire-bombing of 67 Japanese cities. Together with the United Kingdom, and the Republic of China the United States called for a surrender of Japan in the Potsdam Declaration.
The Japanese government ignored this ultimatum. By executive order of President Harry S. Truman, the U.S. dropped the nuclear weapon Little Boy on the city of Hiroshima on Monday, August 6, 1945, followed by the detonation of Fat Man over Nagasaki on August 9.
These two events are the only active deployments of nuclear weapons in war. The target of Hiroshima was a city of considerable military importance, containing Japan’s Second Army Headquarters, as well as being a communications center and storage depot.
