It's a thorough, yet entertaining history of Daniel Ellsberg and his ultimate decision to release the pentagon papers. It's mostly the build up to that decision, the release not occurring until the last third of the film. Except for some unfortunate animation, it's a well made with excellent interviews of important figures from both sides. It's a great documentary of a landmark leak.
