The Cherry Hill Sanitarium isn't a friendly place. The inmates are among the most mentally deranged and dangerous minds known to the world. Patient John Doe can't remember his name, nor much of his past. He's almost certain he's been dead for a while. But John might just be the only person who can stop the madness that is trying to be born in the walls of Cherry Hill. He might be the only chance for the staff and the patients alike. The problem isn't simply that he can't remember how to help them. It's worse than that. John is almost certain that if he does remember his past, the knowledge could very well drive him mad.
