Gene and Fernando, a Mexican patrol captain, learn that Gregorio, an Apache renegade is starting a revolution below the Mexican border, when guns are being smuggled to Arizona. Fernando is to trap Gregorio, while Gene is to put an American who is involved with the smuggling on trial. Pat is hired to transport a bell to San Angelo, not knowing his wagon is carrying an illegal shipment of guns. Gene finds Gregorio, and begins to chase, but has to stop when the renegade crosses over the Mexican border. Fernando allows Gene to unofficially cross the border to capture Gregorio. Gene then discovers the guns hidden in Pat's wagon, and sets out to trap Gregorio. Gene and Fernando both cross the border, and together are able to capture the gun smuggling Apache.
