The Atom Strikes is a document commissioned by the U.S. Army Signal Corps Pictoral Division shortly after the end of the Second World War. It documents the findings of a commission sent to Japan to assess the damage caused by the atomic bombing of Hiroshima and Nagasaki. Nagasaki is then mentioned, with the narrator pointing out how much armament and other military supplies were being produced there, as well as the fact that even civilian homes were used for war work. Nevertheless, the effect of the atomic blast on local schools and churches is also shown.
