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 practioners of the demonic acts that masqueraded as medicine. Now there are no living witnesses. Nothing survived Dr. Vannacutt's excesses; nothing endures except the building in which they occurred. But that building holds all the secrets of its terrible past. Decades after the Vannacutt 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.
