When her sister thought she remembered the person who abducted Elizabeth at knifepoint, John Walsh was a major force disseminating the picture of her abductor. When the police first found her, Elizabeth denied being herself. At the time, everyone wanted to understand why she would act this way, and Steve Hassan was asked to appear on the show with former clients (a mother and daughter) who describe their experience with destructive mind control. There was another guest who had been abducted as a boy.
Included was an excerpt of an interview with of Patty Hearst.
