In the conclusion of a three-part story, the various intrigues at a violence-ridden high school come to head as McCall (Stepfanie Kramer) settles accounts with a gang leader and a philandering teacher. At the same time, Deputy Chief Moorehead (Robert Vaughn) clashes with McCall's boss Devane (Charles Hallahan) over the matter of a self-styled urban vigilante. And Hunter (Fred Dryer) prepares for a showdown with escaped murderess Iris Smith (Cec Verrell) on the "anniversary" of the day he sent her to prison. ~ Hal Erickson, Rovi
