The Devil Worshippers

With Hugh Downs, Anton LaVey, Ricky Kasso, Mike Warnke and Barbara Walters

"The Devil Worshippers" investigates Satanism and focuses on allegations that there are satanic cults committing crimes and murders in the United States. “Police have been skeptical when investigating these acts, just as we are in reporting them. But there is no question that something is going on out there, and that’s sufficient reason for ‘20/20’ to look into it.”
