A mystery pilot, known only as the Eagle, is making treacherous threats in a most unusual way - by writing them in the sky! The creative criminal's intimidation tactics are aimed at a company, which has somehow agitated the mystery man, and now he wants his own type of justice. The word on the street is that Nathan Gregory, a traveling fair owner, is the Eagle's true identity. But when Gregory turns up missing, they begin to doubt that the man disappeared on his own. Determined to reveal the truth, pilot Craig McCoy (John Wayne) vows to unmask the unknown sky-writer before anything else can run afoul. (Echo Bridge Entertainment)
