Unspeakable things happened at the Vannacutt Psychiatric Institute for the Criminally Insane - experiments that brought human torture to new depths of depravity. Secrets that died with their victims and the practitioners of the demonic acts that masqueraded as medicine. Now there are no living witnesses, nothing remains apart from the building in which they occurred. Decades after the Institute was shuttered, five strangers are invited to spend a night there. their reward is a million dollars each. All they have to do is stay alive. It's going to be a long night. A spine-tingling remake of William Castle's 1958 classic horror tale, combines white-knuckle terror with dark humor and cutting-edge-special effects.
