 Dr. Christine Correl is a young psychiatrist dedicated to her job. She is well-trained, compassionate, and sure of her ability to deal with any emotional issue. And then Shane Bello walks into her office. Guilt-ridden, remorseful, Bello begins to unburden himself. Dr. Correl listens with mounting horror as Bello recounts a life dominated by his twin brother Shawn. A life filled with sex, brutality, and murder. Or is it all a lie? Does the twin brother really exist? Or is Shane Bello a clever psychopath bent on claiming another victim? One thing is certain: only one of them is going to leave the office alive
