Lieutenant Colonel John Paul Vann spends ten years (1962-72) in Vietnam. When Vann exposes falsified casualty figures, deceptive battle reports, and other lies about the war, journalist Steven Burnett relays the truth to American newspapers, and Vann takes heat from higher-ups. Meanwhile he's involved with a Vietnamese girl, and his wife is forced to lie so he won't be court-martialed for sexual relations with an underage Vietnamese girl. Back for a second tour, he gets another young Vietnamese woman pregnant and is forced to marry her. Returning in 1965 as a civilian, he's decorated and eventually promoted to general for his contributions during the Tet offensive.
