Private Investigator Nick Jarratt finds himself drawn into a world of the criminally insane and murder by a beautiful auburn-haired woman. She tells him her stepbrother is missing and is desperate to find him, but doesn't want the police involved. Despite this Nick contacts his best friend Detective Pete Drury, who after some digging tells Nick to be wary as this looks like being a lot more than just a simple missing persons case. In the backdrop of a massive killer storm about to hit Melbourne, a jealous and desperate psychiatrist performing illegal procedures in the psychiatric wards of Aimtree House, a private hospital that looks after the mentally ill - and a young man, an escapee from Aimtree, with dangerous multiple personalities stalking the streets of the city, Nick finds himself stepping deeper and deeper into a vortex of deception and brutality as one vicious murder after another leads him to the eventual crazed killer.
