José Aragon, wealthy Texas cattleman, is on a cattle-buying expedition on the Mexican border. After a gueling day looking over the stock, Aragon returns to his hotel, tired and dirty. A beautiful young woman sees Aragon enter the hotel, and, because of his unkempt appearance, believes he is one of the local peasants. She approaches him and asks him to do her a favor. Amused when she offers him five dollars for the errand, Aragon consents to cross the border and pick up a package for her.
