James Reese (Christopher Walken), a misfit G.I. with anger management issues, is driven to a secluded mansion, a hospital-like facility with few patients or staff members. Without explanation, he's assigned to a room with a young American (Ronny Cox) suffering from terminal cancer and bouts of violent behavior. Reese soon realizes that the facility specializes in medical experimentation -- using humans as guinea pigs in brain control research.
