J. Robert Oppenheimer, the Father of the A-bomb, creates the world's deadliest weapon of mass destruction--with the "power of 1,000 suns" it can annihilate tens of thousands in a moment. His scientific brilliance is the power behind the atom bombs used against the Japanese during WWII, but his conscience led him to question the invention that helped end the war. Watch as Oppenheimer paces anxiously in New Mexico while the crew on a B-29 bomber, the Enola Gay, deploys the massive "Little Boy" bomb towards the Aioi Bridge in Hiroshima. The resulting massive loss of life leads Oppenheimer to rethink the way in which nuclear energy was to be used.
