Hawke eagerly joins a mercenary mission to free US POWs in Vietnam, including his long-missing brother Saint John, but looses conscience in a helicopter crash. Awakening from coma, he's told it's been a year and both Dominic and Archanghel perished. He realizes that's a setup, as well as the arrival of StJohn, only after revealing the whereabouts of Airwolf, which he believe no longer needed as price for finding his brother, so he must prevent it being turned over to the foreign conspirators, helped only by a mystery female fake nurse.
