Filmed on location at Lone Pine, CA, this above average Ken Maynard oater features the veteran cowboy star in the title role, a former cavalry officer sent up the river with an accomplice, Bouncer (Nat Pendleton), convicted for failing to pay a restaurant bill. When Judy Brooks (Ivy Merton) announces her intention of running the champion horse Tarzan in the upcoming Big Race, rancher Mark Edmunds (Alan Roscoe) threatens her certain victory by securing ace horseman Austin's release from the chain gang. But Ken overhears Edmunds plotting to sabotage Tarzan and switches sides. Does he win the race on Tarzan instead? Why, of course he does! ~ Hans J. Wollstein, Rovi
