On the United States side of the line dividing Mexico from the United States, the U.S. soldiers camped, with a view to protecting the international line and the citizens of the United States. Fifty yards on the other side the Mexican soldiers were camped to do likewise for their country. One of the bright-eyed senoritas of the southern race captivates two officers, one a captain of her own nationality, the other a lieutenant belonging to Uncle Sam. Both of these men, true and staunch in war and love, have a silent battle to gain the lady’s hand. The captain of the Mexican troops being the older of the two, wins the maid by his quiet love and kindness. The irrepressible, impassioned United States trooper, tries to take the senorita’s heart by storm, but is repelled. On the spur of the moment, to punish his rival, the United States lieutenant tells a falsehood to his commanding officer, and nearly causes international complications, but after coolly analyzing the situation, the lieutenant raises above all petty personal feelings and delivers the captain from jail, returns him to his fiancée across the line, and goes back to take his place and await his punishment.
