In June 1971, Daniel Ellsberg – a leading Vietnam War strategist in the Pentagon – concludes that the war is based on decades of lies and leaks “The Pentagon Papers” to The New York Times and The Washington Post. The 7,000 pages of top-secret documents make headlines around the world. Hailed as a hero, vilified as a traitor, ostracised by his closest colleagues, and called “the most dangerous man in America” by the U.S.’ National Security Advisor Henry Kissinger, Ellsberg risks life in prison to stop a war he helped plan. In this Oscar-nominated film, Ellsberg and a who’s-who of Vietnam-era movers and shakers give a riveting account of those world-changing events, offering a piercing look at the world of government secrecy as revealed by the ultimate insider. Marked by a landmark battle between America’s greatest newspapers and its president – that goes to the Supreme Court – this political thriller unravels a saga that leads directly to Watergate, Nixon’s resignation and the end of the Vietnam War.
