Nefarious

On the day of his scheduled execution, a convicted serial killer named Edward (Sean Patrick Flanery) is visited by psychiatrist Dr. James Martin (Jordan Belfi), who will determine whether or not the man is mentally ill, which would render him incapable of being executed.

During the meeting, which takes many twists and turns, Edward tells Dr. Martin that he's a demon who can possess his body and that the doctor will soon commit three murders of his own.
