SYNOPSIS In the Sevier River mountain area of Utah, horse wranglers Lee and Cuth Stewart, famous for their skill, are unable after several encounters to capture the wild stallion Lightning. Later, in Chicago, where they are seeing the sights, the boys meet and flirt with Dot and Mary, two entertainers who are doing a Topsy and Eva act; by their third meeting the brothers are ready to propose, but the girls leave town unexpectedly with their money and no intentions of marriage. Back in Utah, Lightning, attracted to Lee's pet mare, Bess, invades their camp and takes her away. The boys' pursuit leads them into the desert, which the girls are crossing by airplane; after a forced landing, the boys take the girls "prisoner," putting them to work. The girls escape and almost die in a sandstorm, but Lee and Cuth rescue them and also subdue Lightning; all are happily reunited.
