Giving themselves out to be rebel southerners, the ferocious train robbers joined in the gang led by Frank and Bill Border are loved and protected by the people of Missouri. But Tex and Carson, supported by the Pinkerton Agency, don’t let themselves be charmed by false idealisms. Knocking down thick walls of complicity and silence with difficulty, convincing honest girls and mothers of families that the Civil War is over and that those carried out by the self-styled patriots are only common hold-ups, the pards flush the crooks out of their dens and tighten the circle more and more around the survivors of the criminal gang.
