When the troops were ordered to Mexico, Hilton and Frazer are ordered to the border. Hilton promises Mrs. Frazer that he will bring her husband back safely to her, no matter what condition arises. After their arrival at the border Hilton and Frazer have trouble with the Mexican Indians, who are trying to cross into the United States. Hilton is wounded and Frazer is carried into Mexico by the Indians. Of course, orders have been issued that under no circumstances shall troops cross the border, and in consequence, Hilton, with a few comrades, go as private citizens to Frazer's rescue. How they rescue him, using jobite, the new government explosive; how they cross a yawning chasm by modern military method, and how they explode a land mine, thus cutting off all pursuit, are features which make this film of unusual interest.
