The Devil's Chair (2007)

With a pocketful of drugs, Nick West takes out his girlfriend Sammy, for a good time. When they explore an abandoned asylum, the discovery of a bizarre device, a cross between an electric chair and sadistic fetish machine, transforms drugged-out bliss into agony and despair. After Sammy is brutally assaulted and murdered by unseen forces, Nick becomes the number-one suspect. Years pass and Nick, who had been locked up in a mental hospital, is released into the care of eminent psychiatrist Dr. Willard, who is hell-bent on exposing the truth behind the killing. Accompanied by Dr. Willard and several of his students, Nick returns to the scene of the crime. However, the decrepit asylum hides a blood-drenched secret.
