In Vietnam in 1970, Captain Willard (Martin Sheen) takes a perilous and increasingly hallucinatory journey upriver to find and terminate Colonel Kurtz (Marlon Brando), a once-promising officer who has reportedly gone completely mad. In the company of a Navy patrol boat filled with street-smart kids, a surfing-obsessed Air Cavalry officer (Robert Duvall), and a crazed freelance photographer (Dennis Hopper), Willard travels further and further into the heart of darkness.

Widely regarded as one of the greatest films of all time, this mob drama, based on Mario Puzo's novel of the same name, focuses on the powerful Italian-American crime family of Don Vito Corleone (Marlon Brando). When the don's youngest son, Michael (Al Pacino), reluctantly joins the Mafia, he becomes involved in the inevitable cycle of violence and betrayal. Although Michael tries to maintain a normal relationship with his wife, Kay (Diane Keaton), he is drawn deeper into the family business.
