Lt. Colonel John Paul Vann (Bill Paxton) is one of the first U.S. senior military advisers sent to Vietnam. Vann is as complex as the war itself - a husband and father who takes lovers as casually as he takes control of every situation... except one. In Vietnam, Vann finds himself fighting a war he cannot win alongside a corrupt and demoralized South Vietnamese Army. But what leads a man to expose the truth and sacrifice his career? To fly from a loving home to a war-torn battlefield? To turn from a soldier of strategy to a general of ruthless bombing campaigns which can only destroy what they cannot defeat?
