 The Firm asks String to covertly shuttle a renowned researcher and diplomat, Dr. Roger Burton (Donald Hotton), to Russia for a secret meeting since Airwolf can get past the Russian defenses without being detected. Unfortunately, before Hawke can go back and recover Dr. Burton, a virus implanted by Airwolf s creator, the late Dr. Moffett (David Hemmings), rears it s ugly head and threatens not only the destruction of the supercopter but the elimination of the Firm as well unless a computer programmer String knows can undo the damage the evil Dr. Moffett concocted.
