In cooperation with a top-secret government agency called the Firm, renegade pilot Stringfellow Hawke (Jan-Michael Vincent) and his buddy Dominic (Ernest Borgnine) carry out dangerous military missions at home and overseas aboard the heavily armored, high-tech helicopter Airwolf. After moving from CBS to the USA Network, this action adventure series welcomed an all-new cast, which featured Barry Van Dyke as String's long lost brother.
