He is paired up with veteran detective Bill Malloy (Robert Loggia) in order to find and stop a serial killer. The killer is Arthur "Buck" Taylor (Judd Nelson), the son of a former LAPD cop whose motive for killing is frustration over not having been accepted to the force and failure in the eyes of his father.
