A mind game of a movie based on a screenplay by Twilight Zone contributor Charles Beaumont, it follows an experimental brain researcher (Bill Pullman - Lost Highway) who agrees to dig into the gray matter of a schizophrenic scientist (Bud Cort), only to fall prey to his patient's psychosis. Pullman's ordeal takes one hairpin turn after another as he becomes lost in a maze of alternate realities, no longer able to sort fantasy from reality or paranoia from persecution. Bill Paxton (Big Love) costars as a smarmy corporate manipulator.
