Plot

The film depicts the actions of U.S. troops stationed on the boundary dividing the United States from Mexico "with a view to protecting the International line and the citizens of the United States." On the other side of the border, Mexican soldiers are "camped to do likewise for their country." In this highly charged climate "one of the bright-eyed senoritas from the southern race" has captivated an officer from each side. The Mexican captain, played by Fielding, wins her hand via "quiet love and kindness," while "the irrepressible, impassionate United States trooper tries to take her heart by storm." By bringing the U.S. regiment into conflict with the Mexican troops, the rivalry "nearly causes international complications."
