The outlaw El Tigre and his gang have been repeatedly crossing the border into Texas, robbing and killing. In Border City, a ranger is asked to break up the gang, and he heads to Mexico. On the way, he meets up with a young man from New York, who is on his way to San Clemente in search of his brother, and the two travel into town together. But the brother is heavily involved with the gang, and he is not happy to see either of the visitors.
