Westward Ho (1935)

Young John Wyatt witnesses his parents’ murder and his brother Jim’s abduction by Ballard's outlaw gang. Fast forward to post-Civil War California, John has formed a vigilante group called The Singing Riders, a band of white-hatted horsemen who patrol the trails, seeking justice for the wrongs of their past. As fate would have it, John unexpectedly reunites with Jim, now a spy for the very gang that tore their family apart. Complicating matters, both brothers find themselves in love with the same woman, Mary Gordon, as tensions rise toward a fateful confrontation.
