Law of the Pampas

Hoppy (William Boyd (actor)) and his pal Lucky (Russell Hayden) head to South America to look after a herd of cattle sold by Cassidy's boss to an Argentine rancher. Villain Ralph Merritt (Sidney Blackmer) wants to get his mitts on that cattle, and he's not above hiring the scum of the earth to do his bidding. Fortunately, Hoppy, Lucky and their new Latin American buddy Don Fernando (Sidney Toler) make short work of the bad guys in an outsized barroom brawl.
