How do you kill an idea? Across the dusty plains of America's southwest, a deadly storm is brewing. A string of murders portend the sinister designs of an infamous terrorist to bring about the end times.

Indoctrination explores America's terrifying underbelly-of death cults and sleeper cells, serial killers and apocalyptic nightmares.
