Sam Swift and his partner, Jose Martin, run a fixed base operation at a small regional airport in central Texas. They specialize in the restoration of antique aircraft, and they own a P-51D Mustang and a Mitchell B-25 medium bomber, both from WWII. When they contract to restore a German Messerschmitt BF-109 fighter of the same era, strange things begin to happen. At first it is only misplaced tools and small items, aircraft mysteriously moved, and the arrival of Messerschmitt parts they had not ordered. Is it possible that having mortal enemies in the same hangar has roused the ghosts of their wartime pilots, one with a goal of making ace with his all-important fifth victory?
