Hawke meets a mercenary who claims to have information regarding his missing brother. When they part company, Hawke loses consciousness in his helicopter and crashes. When he comes to, he finds himself in a hospital. The medical staff inform him that he has been in a coma for the better part of a year. His friends, Archangel and Dom, were killed on a POW camp raid, but in the process, their heroism helped rescue Hawke's brother Saint John. Believing that his "mission" is over, Hawke reveals the location of Airwolf to his captors, then discovers that it has all been an elaborate ruse and he has inadvertantly turned over the super copter to a group of foreign conspirators.

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...
