About to be sent to a small country in Central America, Buck, Sonny and Tumb are given a special briefing by two high-ranking US government agents. Under the cover of their official mission, to train Managuan Air Force pilots in the use of their brand new F-18s, the three men are to try and overfly a strangely modern airfield suspected of belonging to a drug cartel. Problem: the airfield is in the middle of a no-fly zone.
