The station house receives an urgent radio call from an unidentified officer--which is abruptly cut off after he says "shots fired." The radio dispatcher quickly sets up a roll call to determine the officer's identity, and by episode's end Pete Malloy (Martin Milner) is among the cops who have gathered to defuse a hostage situation in a parking garage. Elsewhere, Malloy's partner Jim Reed (Kent McCord) has gone undercover to smash up a gang of thieves who prey on pizza delivery drivers. ~ Hal Erickson, Rovi
