While demonstrating the capabilities of the new prototype supercopter codenamed 'Airwolf', Dr. Charles Moffet goes rogue, steals the chopper and kills almost all of the observers. At least one man -- Michael Coldsmith Briggs III survives. Briggs, codenamed 'Archangel' is the head of a covert organization called 'The Firm' and Archangel calls upon the one man in the world he knows that can retrieve the copter. The problem is Stringfellow Hawke is not only a loner, but a recluse as well. The amount of money the Firm is willing to pay for Airwolf's recovery is irrelevant. Hawke wants just one thing - the safe return of his brother, Saint John, who was captured during the Vietnam war and is evidently a POW.
