This film takes a comprehensive look at the release of the Pentagon Papers in 1971 and the resultant political firestorm that may have sealed Americans' disenchantment with the war, and which certainly sealed the fate of the Nixon administration.

The film is also an intensely intimate look into the conscience of a gifted and intelligent man who National Security Advisor Henry Kissinger told his staff was "the most dangerous man in America who must be stopped at all costs" upon his leaking of the Pentagon Papers to The New York Times and who wrestled personally and professionally with what he came to see as the contradictions between American ideals and American power in Southeast Asia.
