"The Most Dangerous Man in America" is the story of what happens when a former Pentagon insider, armed only with his conscience, steadfast determination, and a file cabinet full of classified documents, decides to challenge an "imperial" presidency – answerable to neither Congress, the press, nor the people – in order to help end the Vietnam War.
