Ken Bledsoe, aka The Pocatello Kid, escapes from prison to clear his name after being wrongly accused of a crime committed by his twin brother Jim. He heads to his brother's town, where Jim is now the sheriff and is secretly leading a gang of rustlers.
The Pocatello Kid
When a wounded Pocatello flees from the Sheriff after his brother's murder, Larkin takes advantage of the situation by switching their identities, forcing Pocatello to adopt his brother's outlaw persona.
