Tex Hartwell comes to the aid of an old cobbler by protecting him from the blows and insults of Jim Mackey, a skinflint banker. Mackey orders his hired guns to get Tex, but Tex is too quick for them. On the strength of his fast draw, Tex is hired as a trail rider by Dee Winch, being given the job of keeping diseased cattle off Winch's grasslands. Mackey's men later stampede a herd of infected cattle onto Winch's land, and Tex is fired in disgrace. Fanny Goodnight informs Tex that Mackey is the leader of the cattle runners, and Tex forces him to sign a confession to that effect. The old cobbler later kills Mackey, Tex is cleared with the cattlemen, and he and Fanny decide to ride a trail of their own together.
