Former silent screen serial queen Dorothy Gulliver stars in this very low-budget Western as the owner of a mine terrorized by a gang of ruffians. Looking into several troubling occurrences at the site, including the murder of a mining engineer, Pat (Gulliver) learns that Devil Jackson (George Chesebro) and his henchmen are using the location for their counterfeiting operations. Happily, a couple of undercover agents, Joaquin (Rex Lease) and Pedro (Earl Douglas), are present to save Pat from certain death in the hands of the gang. Fighting Caballero was released by an outfit calling itself Superior Talking Pictures, Inc. -- a distinct misnomer. ~ Hans J. Wollstein, Rovi
