Sagebrush Heroes (1945)

This Columbia western starring Charles Starrett finds Steve Randall (Charles Starrett) forming a radio show with Jimmy Wakely (Jimmy Wakely) and his Saddle Pals, and are in town for a rodeo. Reporter Connie Pearson (Constance Worth) persuades them to visit Marty Jones (Elvin Fields), a fatherless boy, who has been sent to a boy's home after stealing Steve's wallet, ran by Tom Goodwin (Forrest Taylor.) Marty tells Steve that the home is a phony and is a front for cattle rustlers. Steve passes the information on to Connie, who doesn't believe him, so he and Jimmy wire the ranch for sound. They are caught and Goodwin turns them over to Sheriff Barnes (Edmund Cobb), and then plans to skip the country
