Synopsis by Hal Erickson
Singing cowboy Monte Hale rides back into view in Republic's South of Rio. Borrowing a page from Hollywood's gangster-flick lexicon, Hale tackles a group of protection racketeers who were responsible for his dishonorable discharge from the Arizona Rangers. Making things dicey is the fact that one of the gang members (Douglas Kennedy) is Monte's own brother. The fact that Roy Barcroft is the head of the crooks comes as no surprise; it is surprising, however, to find traditional comic relief Paul Hurst in a relatively straight role as a newspaper reporter. South of Rio was one of several Monte Hale starrers directed by Philip Ford, the nephew of John Ford.
