Hunter (Fred Dryer) goes after an insane killer who, disguised as a police officer, preys upon teenage prostitutes. It isn't exactly "business as usual" for Hunter; the detective has a personal stake in the case. One of the hookers whom the killer plans to knock off is 18-year-old Debbie Small (Bryan Horrocks), who had befriended Hunter in the earlier episode "City Under Siege". ~ Hal Erickson, Rovi
