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.

A rich corporate industrialist, Carter Anderson III, hires Santini and Hawke to ensure his safe transportation needs when it becomes evident that he might be targeted for a hit. Anderson is aware of the existence of Airwolf and Hawke agrees to use the supercopter to help protect Anderson if necessary. Caitlin agrees to fly one of the helicopters for the mission, but there's a twist that she's unaware of; her new boyfriend just might be in on the assassination plan.
