You are William Redmoor, recent recipient of a radical brain operation intended to cure psychosis and current inmate at a clandestine treatment centre for the criminally insane. Your memories are fuzzy, but it appears that your wife was murdered, and the evidence pointed toward you as the killer. Here at the Bright Dawn Treatment Centre you are under the care of an enigmatic figure known only as The Doctor. Whatever The Doctor's methods, they appear to work - your psychosis is gone... or is it?

Demons you once battled have appeared once again. Worse, it seems that The Doctor has some diabolical scheme to perform experimental operations on scores of other inmates. You must not only survive an onslaught of horrific beasts but also stop The Doctor from achieving his goal. With all the insanity that surrounds you, you can't tell if it's you or the world around you that has truly lost it. Just how demented are you? Time to prepare for phase two...!
