Hardcore is a 1979 American drama film written and directed by Paul Schrader and starring George C. Scott. Writer-director Schrader had previously written the screenplay for Martin Scorsese's Taxi Driver, and both films share a theme of exploring an unseen subculture.
Jake Van Dorn (George C. Scott) is a prosperous local businessman in Grand Rapids, Michigan who has strong Calvinist convictions. A single parent, Van Dorn is the father of a seemingly quiet, conservative teenage girl, Kristen, who inexplicably disappears when she goes on a church-sponsored trip to California. A strange private investigator, Andy Mast (Peter Boyle) from Los Angeles, is hired, eventually turning up a 8mm stag film of his daughter with two young men.
Van Dorn then suspects that his daughter was kidnapped and forced to join California's porno underworld. His quest to rescue her takes him into an odyssey through this "adult" underground.
