Singing cowboy Rex Allen and his faithful horse Koko head the cast in Border Saddlemates. This time, Rex in on the trail of counterfeiters (Republic's favorite villains of the 1951-52 season). Criminal mastermind Steve Baxter (Roy Barcroft) is smuggling fake money across the Mexican border while using a fox farm as a cover. But Rex ends up (here it comes!) out-foxing Baxter in the exciting finale. Virtually the same plotline was used in the concurrently-released Republic oater Wild Horse Ambush, even unto casting Roy Barcroft as the villain (but then, wasn't he always the villain?) ~ Hal Erickson, Rovi
