Dr. Michelle Ward goes behind bars to interview violent murderers and offer insight into what drives people to kill. From her early doctorate research on psychopathy, to her ongoing study of criminal behavior, she possesses a unique ability to push murderers to the limit, getting them to admit things they wouldn't confess to anyone else. She is trained to go beyond excuses and get to the psychological core of why people commit heinous acts - and she does it alone in a room, face-to-face with coldblooded killers.
