The Cherry Hill Sanitarium isn't a friendly place. The inmates are among the most mentally deranged and dangerous minds known to the world. It's the sort of place that sane people would do well to avoid, if they value their lives.

John Doe is not a normal man. He can't remember his name, nor much of his past. He's almost certain he's been dead for a while, and that the asylum that has become his residence is haunted by more than broken minds and twisted memories.

John isn't wrong. Something dark is growing inside the walls of the asylum, something that festers and hungers to be free of its prison. That something has never lived before, but it wants to live now, even if it has to destroy everything it encounters to get its way.

John Doe might just be the only person in the world who can stop the madness that is trying to be born into 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 Doe is almost certain that if he does remember his past, the knowledge could very well drive him mad.
