Chris Taylor is 21-year-old college student who in 1968 quits school to volunteer for the Army. He's shipped off to Vietnam, where he serves with a culturally diverse group of fellow soldiers and under the two men who lead the platoon: Sgt. Barnes, whose facial scars are a mirror of the violence and corruption of his soul, and Sgt. Elias, who maintains a Zen-like calm in the jungle and fights with both personal and moral courage even though he no longer believes in the war. After a few weeks "in country," Taylor begins to see the naïvete of his views of the war, especially after a quick search for enemy troops devolves into a round of murder and rape.
