Through a combination of bad luck and a bad temper, working-class moving man Pepper finds himself wrongfully committed to New Hyde Psychiatric Hospital - an institution filled with those society would rather forget. There, he must contend with patients working against him, doctors harboring grim secrets, and perhaps even the Devil himself. As Pepper navigates a hellscape where nothing is as it seems, he finds that the only path to freedom is to face the entity which thrives on the suffering within New Hyde's walls - but doing so may prove that the worst demons of all live inside him.
