When Casey and two of her friends go to the mall they're abducted by an unsuspecting and nervous looking man. When they awake the three girls find themselves locked away in a room, each with a camping mattress for a bed. The room is bare and they have no idea what's going on and they all fear for their lives.
Though they're free to roam in their room and bathroom, there's no windows and the only part of the world they can see from inside is through a small gap in the door which leads onto another room. As they peer through the small hole, they see a pair of high heeled shoes and immediately see the legs of a woman. Knowing that they were abducted by a man, the girls call out for help and what they find frightens and perplexes them all.
The person who comes to the room isn't a woman, it's their kidnapper and in a soft voice he tells the girls not to worry as 'he's not allowed to touch you' and goes on to say that the kidnapper 'listens' to her.
The man behind all the mystery is called Kevin. A middle-aged bald headed man named Kevin who endures the symptoms associated with Dissociative identity disorder - a severe case as Casey soon identifies numerous personalities, 20 plus and counting. Amongst the personalities are more innocent beings such as Hedwig, a nine year old boy; to someone the girls are truly terrified to meet, known only by the nickname 'the beast'.
The teenagers know they must find a way to overpower their captor and escape before the beast fulfils his mission and the girls are lost for good.
