Synopsis by Hans J. Wollstein
Eschewing action in favor of humor, this Hopalong Cassidy series entry has the usually black-clad hero (William Boyd) changing into dude apparel in order to investigate what ails the town of Del Oro, NM. Aligning himself with the ramshackle medicine show of Doc Rufus Bates (Earl Hodgins), proprietor, Hoppy quickly learns that everyone's favorite old lady, Ma Burton (Marjorie Rambeau), is in reality the ruthless leader of a gang of mine robbers. Convincing Ma that he is a former convict, Hoppy enlists the gang in a scheme to rob the Gardner silver mine but the plan goes awry when Ma overhears Hoppy's rookie sidekick, Lucky Jenkins (Russell Hayden), spill the beans to Paula (Bernadene Hayes), Doc's daughter. After escaping a fire at the mine, Hoppy and Lucky manage to bring both Ma and her henchmen to justice.
