Luke Adams is your stereotypical 'good looking businessman' - dark hair, dark eyes and stubble lining his chiselled jaw. He is a successful businessman, breaks girls hearts, is wealthy and has the arrogance to match. But when he finds himself in an abandoned hospital with nothing but white walls, everything changes. He has no idea where in the UK he is, no idea what he's doing there, and no idea what goes on beneath the depths. All he knows is that something is going on that's not supposed to, and he's next.
