In a race against the Nazis to develop an atomic bomb, the USA assigned leading scientists like Albert Einstein from all over the world to The Manhattan Project, an incredible scientific, engineering and manufacturing feat which would have everlasting global consequences. This documentary examines the Manhattan Project through government files, archival footage and accounts of surviving members of the developing team, including  Paul Tibbets, pilot of the Enola Gay, and directors of the Oak Ridge National Laboratory. Allthough the atomic bomb was never officially used after worldwar 2, the potential danger and risk is still there and shold not be underestimated.
