The homicide detectives team up with the FBI to track down a serial killer who is moving progressively northward on I-95. The combined law officers manage to capture a man (Jeffrey Donovan) who fits the description of the killer perfectly -- only to find out that they might have the wrong person in custody. And in another development, Giardello (Yaphet Kotto) has an awkward meeting with his estranged daughter. The role of TV reporter Dawn Daniels is played by Rhonda Overby, a real-life correspondent for Baltimore's NBC affiliate WBAL-TV. ~ Hal Erickson, Rovi
