Cannon is hired by a man concerned that his daughter is involved with a cult of college-age kids. They have a hold on her, or at least the leader of the cult - chillingly played by john Rubenstein - has. Cannon learns a chilling plan: the plan to kill the teen girl's parents. Already a drunkard got killed, a lab blown and they even try to kill Cannon with a crossbow. There's a neat twist in the end, which reveals the reason why the cult leader wants the girl's family dead. This is an absorbing and effective thriller with really good atmosphere. It's also a good view of the era. It can be sinister and disturbing especially with what happened a few years previously to this but it's a solid episode.
