Art class schoolmates Casey, Claire and Marcia are about to embark on a journey into pure nightmare, when after a birthday party at Philadelphia's King of Prussia Mall, they will be drugged and abducted in plain sight at the Mall's parking lot by Dennis, one of the 23 suppressed personalities residing in Kevin Wendell Crumb's body. Undoubtedly, Kevin is a shattered man and a rare case of the confirmed, yet, controversial Dissociative Identity Disorder, which to some, is the doorway to the obscure corners of the human psyche. With a plethora of diverse "alters" ranging from extroverted leaders to artistic fashionistas, to a nine-year-old boy and even to a meticulous, stern woman, no one could really tell what the predator's true intentions with his captives are, nevertheless, one thing is for certain: from the horde that plagues Kevin, some identities are inevitably more sinister than others. Sooner or later, the elusive 24th "Beast" persona, who's been secretly nurtured in the background, will emerge in all its glory as an amalgam of qualities and the highest form of human evolution. Could the "Beast" be only a fantasy?
