Cast & Crew
Lane and Buck Hallett have spent their lives trying to make restitution for cattle stolen by their father stole. Each brother wears a Stetson hat emblazoned with different brands that signify the ranches from which their father stole cattle. Lane is shot and hunted after he is suspected of killing a sheriff, but he is innocent. Buck leaves Lane in the care of Joaquin, a trusted friend, while he tries to find the real murderer. In the meantime, Quayle, an untrustworthy character, plans to hunt Lane to obtain a reward. Tex, a friend of the Halletts, makes a deal with Quayle to find Lane, but plans to keep an eye on Quayle's movements so he can protect Lane. Buck sets Lane's horse free, hoping he will lead him to Los Canada, the ranch run by Rose Porter, with whom Lane is in love. Some ranchers recognize the horse and corral it, and Rose's foreman finds Buck and takes him blindfolded to Los Canada, where he is kept captive in a cabin. On Tex's advice, Joaquin removes Lane from the hideout in the sandflow to protect him from Quayle. Buck escapes from the cabin and overhears a discussion about the failure of the Porter bank and realizes Rose's father, who owns the bank, became mentally unstable after the bank's failure. Finally trusting Buck, Rose confesses that her father shot the sheriff. Rose's foreman captures Quayle, but he escapes and kills her father. Buck finds Quayle in time to save his brother, and after a struggle, Joaquin appears and renders Quayle unconscious. After all is righted, Buck and Joaquin leave Los Canada to pay their final debt to the Porter ranch. The ranch is now owned by Rose, however, who relieves them of their debt and invites Lane to stay on with her.
