Billy Carter and two Mexicans, Cuteo and Estaban, are smugglers of opium which they bring across the border from Mexico into the United States. The authorities are unable to apprehend them, so "Pinnacle" Bill and "Cheyenne" Harry of the Arizona Ranger Service are sent to assist the sheriff, Dan Beckham, and the inspectors in their search.
