In the conclusion of a two-part story, Officers Jim Reed (Kent McCord) and Pete Malloy (Martin Milner) continue their temporary assignment with an ASD helicopter unit. Assisted by airborne officers Walters (William Stevens) and Mills (Gavin James), the two normally "grounded" cops are able to hunt down and capture some very elusive robbery suspects who have escaped by plane. Inasmuch as most of the episode's exposition is delivered via the helicopter radio, guest actors Sam Edwards, Julie Bennett and John Nolan are heard but never seen. ~ Hal Erickson, Rovi
