From IMDb:
Kelly Jordan (Robert Lowery) and Andy Melton (Robert Kent) are former AAF fliers operating a cargo service over the South American mountain ranges in order to get enough money to return to TEXAS and buy a commercial line. Andy is killed when his overloaded plane crashes and explodes. Kelly meets Laurey Roberts (Ann Savage), who gets him to take her to the mining-camp operation as a cook, as she is running away from her ex-husband, Tom Hammond (Douglas Fowley), who has just been released from prison. Hammond catches up with Laurey, but he is killed in a gun fight, and Kelly and Laurie leave looking for a peaceful life in TEXAS.
