A photographer propelled to explore his dark side begins tracking a subway serial killer whose brutal butchery makes for the most nightmarish images ever captured on camera in director Ryuhei Kitamura's adaptation of a short story by horror heavyweight Clive Barker. Leon Kaufman (Bradley Cooper) is just another struggling photographer in search of the perfect subject. Encouraged to explore the sinister side of humanity by a prominent art gallery proprietor (Brooke Shields) who is set to display his upcoming debut, Leon goes against the wishes of his girlfriend, Maya (Leslie Bibb), and begins stalking notorious serial killer Mahogany (Vinnie Jones) -- whose sadistic murder spree has been making headlines all across the country. As Leon's fascination with Mahogany gradually grows into obsession, his descent into the killer's putrid world of murder begins to corrupt his soul while simultaneously dragging his concerned girlfriend down a perverse path of darkness from which there is no return.
