In a twist for the straight and narrow Hopalong Cassidy, the movie starts when he comes to the aid of Belle Starr (Natalie Moorhead) who has returned to her ranch after serving time in jail. Then again, he doesn't tolerate crooked lawmen either. Gabby's wit and wisdom starts when he's snookered by the Stagecoach driver (Robert McKenzie), "Wizzled by a no-count ornery mule skinner." Hoppy's ace right hand man Lucky (Russell Hayden) plays a great balancing act having to prove himself to Buck Peters (John Elliott), owner of the Bar 20 Ranch and fighting for the affections of Belle's daughter Jacqueline (Dorothy Short). Unbeknownst to Belle, her foreman Ringo (Stephen Chase) is a cattle rustler as the plot thickens. Billy King plays Artie, nephew of Buck Peters (John Elliott). Billy and his horse Tony had become well-known in horse shows and Hoppy was happy to have them on contract in four of his films.
