Water Rustlers plot
"THE SINGING COW GIRL! She Outrides...Outshoots...Out sings them All! Thrill to the Brave Adventures of this Darling Songbird of the West!"
Musical rancher Shirley Martin determines that Robert Weylan has diverted the course of the river into the valley, causing her livestock to die from lack of water. Shirley and her foreman Bob Lawson therefore go to court. They lose the lawsuit because Weylan's henchmen intimidate the local ranchers into not testifying against him. But Shirley thinks he has a good plan to get the water flowing again through the valley.
