During the height of the Vietnam War, Captain Willard (Martin Sheen) journeys upriver on a perilous and increasingly surreal odyssey to assassinate the renegade Colonel Kurtz (Marlon Brando), a once-promising officer now operating with godlike impunity in the jungles of Cambodia. Francis Ford Coppola's haunting, hallucinatory epic is cinema at its most audacious and visionary.
