Border Guns

A cowboy drifts into an Arizona border town and finds himself in the middle of a fight between the townspeople and a Mexican bandit gang that has been terrorizing the territory. Bill Harris, looking for border rustlers and working undercover, rides into town and makes friends with Fred Palmer, one of the rustlers. They both take an interest in Jane Wilson. When the boss of the rustlers learns of Bill's true identity, he uses their attraction to Jane to alienate the friends hoping Fred will kill Bill.
