chunk: In 1967, during the Vietnam War, Army Special Forces Colonel Walter E. Kurtz (Marlon Brando) has become insane and now commands his own Montagnard troops, inside neutral Cambodia, as a demi-god. Colonel Lucas (Harrison Ford) and General Corman (G.D. Spradlin), who are growing increasingly concerned with Kurtz's renegade operations, assign U.S. Army Captain and Studies and Observations Group veteran Benjamin L. Willard (Martin Sheen) to terminate the Colonel's command with extreme prejudice.
