Dr. Cara Harding is a dedicated psychiatrist skeptical about the nature of certain afflictions, especially Multiple Personality Disorder. Her skepticism starts to give way when her father, Dr. Harding, introduces her to a patient named Adam who consistently assumes the personalities of murder victims. Cara's work with Adam puts her and her daughter Sammy at risk of becoming victims themselves.
