nova-63 Alibi happens upon a young man who has been attacked and left for dead. The young man, Bret Travis, begins to recover and tells of how he is travelling to a ranch that he has inherited. The problem is the only person who can verify his identity is the lawyer who contacted him. The lawyer is a man named Denby (Glen Strange). The Range Busters fear for young Travis' life so they decide to scout the ranch and investigate Denby.Crash poses as a workman and gets a job as a foreman inside the ranch. Dusty pretends to be an old friend of the recently deceased owner of the ranch and he is invited to stay. From the inside the duo quickly learn that Denby is a crook. He has another man impersonating Travis so he can get control of the ranch. Just why does Denby want the ranch so badly? The Range Busters see it as a modest place not really worth Denby's attention. The answer to that question comes when the Range Busters find a spot in the land where oil is busting through. Evidently the land is rich in oil.
