Chris Cuomo conducts the last interview that serial killer Andrew Urdiales will ever give. Was he insane? Did he hate women? What went wrong in his childhood to turn this man into such a monster?

In 1987, a group of teens, hell-bent on revenge, killed local businessman John Hill who had raped their friend Jennifer. 30 years later, Chris Cuomo speaks to Lisa Harris, the only member of the group who was sentenced to life in prison.
