In the second episode of a three-part story, Hunter (Fred Dryer) continues his search for a serial killer who preys on authority figures, beginning with a phy-ed teacher at a violence-ridden high school. Meanwhile, a mysterious neighborhood vigilante has been targetting those whom he regards as criminals who have slipped through the cracks of justice. And while working undercover as a teacher, McCall (Stepfanie Kramer) is exposed by the leader of a teenage gang which uses high-tech weaponry. ~ Hal Erickson, Rovi
