In one of his last film roles, legendary B-Western cowboy Sunset Carson roots out the varmints responsible for a false smallpox scare. After arriving in the small town of Quartzville, Carson determines that a crooked lawyer-and-doctor team created a false smallpox epidemic in order to seize a gold mine from an old man and his family.

Scanlon is pulling off a land swindle by selling lots in a ghost town claiming the power company is bringing in a line. As a bonus he throws in shares in a worthless gold mine.

Filmed back-to-back with three other Sunset Carson vehicles in 1947, this Yucca Pictures Western starred the former Republic cowboy as a Texas Ranger chasing a gang of rustlers into the notorious outlaw territory of Three Corners. Attempting to sabotage the proposed annexation of the territory, desperado Bart Dawson (Stephen Keyes) and his men ambush Sunset and his young trainee Jed (Al Terry). The villains, who have been terrorizing pretty trading post operator Helen Bennett (Patricia Starling), are eventually defeated by the rangers in a violent gun battle and the planned annexation takes place on schedule. For all intents and purposes, the handsome but wooden Sunset Carson ended his screen career with this series of extremely low-budget Westerns, originally filmed in 16mm and released by that dumping ground of Poverty Row flotsam, Astor Pictures.
