Toward the end of the Second World War in the Pacific there were several top secret-bombing missions. This story is about an ultra top-secret mission regarding a B-29 Superfortress that launched from an airstrip on Saipan in the evening of April 3, 1945. The plane disappeared somewhere over the Pacific; it was carrying the first Atom Bomb. This is also the story of closure for the family survivors of the missing airmen.
