Carl Thompson is a murderer and criminal hiding from justice behind the Mexican border.
Carl Thompson is more than just a criminal, he's a minor tyrant who has been holding the Mexican town of Paso Alto hostage through murder and intimidation.
After he and his gang commit a bank robbery and murder in Twin Pass and escape back across the border, Thompson thinks he's safe from the law. But another kind of justice arrives for him in the forms of a tall, dark-haired cowboy and his wise-cracking friend.
Thompson gives the pair an hour to leave town. The two men don't scare easy and, unfortunately for Thompson, their courage is infectious. Soon, the townspeople are riled up enough to rise up against the blond-haired criminal and his gang. One gun battle later and Thompson is tied up and on a horse headed back to the US to face a murder charge.
