When new hi-tech attack chopper HX1 is stolen by an elite group of mercenaries, the tactics used fits those that Hawke's MIA brother St. John was trained in, and Hawke is certain that his brother may somehow be involved. Dominic begs him to leave well alone, but Hawke is adamant, and with Archangel insisting that if it cant be retrieved, the Firm will blow HX1 and anyone flying it out of the sky, Hawke goes back into his past and some of the people he knows from it, to desperately try and get a lead on the group and mercenaries and possibly St. John... But the HX1 is so powerful, it may even be able to blow Airwolf out of the sky...
