The film tells the story of J. Robert Oppenheimer (1904–1967), the theoretical physicist who led the effort to build the first atomic bomb, tested in July 1945 at Trinity site in New Mexico. It features interviews with several Manhattan Project scientists, as well as newly declassified archival footage.
The film's title comes from an interview seen near the conclusion of the documentary. Robert Oppenheimer is asked for his thoughts on Sen. Robert F. Kennedy's efforts to urge President Lyndon Johnson to initiate talks to stop the spread of nuclear weapons. "It's 20 years too late," Oppenheimer replies. After a pause, he states, "It should have been done the day after Trinity."
