An epic mosaic of many interrelated characters in search of happiness, forgiveness, and meaning in the San Fernando Valley.

In the San Fernando Valley in 1977, teenage busboy Eddie Adams (Mark Wahlberg) gets discovered by porn director Jack Horner (Burt Reynolds), who transforms him into adult-film sensation Dirk Diggler. Brought into a supportive circle of friends, including fellow actors Amber Waves (Julianne Moore), Rollergirl (Heather Graham) and Reed Rothchild (John C. Reilly), Dirk fulfills all his ambitions, but a toxic combination of drugs and egotism threatens to take him back down.

Freddie Quell (Joaquin Phoenix) is a troubled, boozy drifter struggling with the trauma of World War II and whatever inner demons ruled his life before that. On a fateful night in 1950, Freddie boards a passing boat and meets Lancaster Dodd (Philip Seymour Hoffman), the charismatic leader of a religious movement called the Cause. Freddie tries hard to adhere to Dodd's weird teachings and forms a close bond with his mentor, even as other members of Dodd's inner circle see him as a threat.
