Arizona Round-Up

Undercover government agent Tom Kenyon is hired by rancher Mike O'Day to help protect his herd of wild stallions. Tom smells a rat when a railroad syndicate suddenly quadruples their rates, fully aware that the ranchers will not be able to afford to transport their horses to market. The syndicate plans to bankrupt O'Day and the others, in a plot to buy up their land cheap. Tom must find a way to derail the scheme, before a bloody shooting war erupts.

Tom Keene made a career out of playing self-assured cowboys who relied more on their clever wits and cunning than on their fists and firearms. His handsome smile and rugged physique garnered him legions of loyal fans. One performance nuance noted: each time he fires a lethal shot that kills a bad man, he beams a broad grin as if to congratulate himself on his marksmanship.

Bonus: vintage cowboy trailers
