Northwest Stampede (1948)

"THRILL to the most daring death duel ever filmed---the "White Outlaw" battling a snarling, fear-crazed wolfpack!"

In this romantic western, the real stars are a mustang and a police dog. The human aspect of the story centers on a rodeo rider whose late father bequeathed him a ranch in Calgary, Canada. The rider really tries to settle down to ranching, but finds himself pining for the rodeo. His forewoman, also a former rodeo performer, thinks her employer is shirking his duties and needs to forget about broncos, and bull-riding and settle down. Meanwhile, the fellow also longs to catch the white stallion running wild. The dog helps out.
