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.
