Dave Kent, a commercial aviator, and his mechanic, Skeets Smith, are forced to make an emergency landing in Mexico and find themselves in the hands of La Panthera, a notorious bandit who wishes to overthrow the government and become president of a new republic. Manuel, his chief henchman, obliges them to collect the booty in a robbery, but Kent manages to meet María Valdez, a prisoner--held for marriage to the insurgent leader--who implores his aid. Kent and Skeets are arrested for the robbery and sentenced to death.
