NEFARIOUS is a supernatural thriller. A skeptical psychiatrist, Dr. James Martin, takes the place of another psychiatrist who committed suicide. Dr. Martin has to interview a condemned serial killer to see if he’s sane enough to be executed. The prisoner tells the psychiatrist that he’s a demon called Lord Nefarious. Martin asks Nefarious to prove that he’s a demon, but he gets more than he expected by making such a foolish demand.
