The Firm asks String to covertly shuttle a renowned researcher and diplomat, Dr. Roger Burton, 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, rears its 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.
