Daniel Ellsberg, a hawkish analyst for the Rand Corporation think-tank and later for the U.S. government, supports the war in Vietnam until two powerful occurrences: the experience, first-hand, of combat and political turmoil in Vietnam, and the discovery of secret Defense Department documents detailing the deliberate fabrication of reasons to initiate and expand the war. Facing a crisis of conscience, Ellsberg becomes convinced that the American people have not been told the truth about the war, its justifications, or its likely outcome.(imdb)
