Tex Hartwell (Buck Jones) rescues an old cobbler from the physical assault of corrupt banker Jim Mackey (Carl Stockdale). When Mackey orders his hired guns to kill Tex, the stranger outdraws them. Rancher Dee Winch (Jack McDonald) is impressed with Tex's fast draw and hires him as a trail rider, tasked with keeping diseased cattle off of his land.

Sometime later, Mackey's men stampede a herd of infected cattle onto Winch's land. When Winch learns of the infected cattle, he fires Tex, who leaves in disgrace. Meanwhile, Tex learns from Fanny Goodnight (Lucy Fox) that Mackey was behind the stampede of infected cattle. Tex confronts the corrupt banker and forces him to sign a confession admitting to his guilt. Later, the old cobbler kills Mackey, Tex's reputation is restored with the cattlemen, and he and Fanny ride trail together on their own.
