The Money Corral.

Cowhand Lem Beason wins a shooting contest at a Western rodeo, and as a result is hired by railroad president Gregory Collins to return to Chicago with Collins to take charge of security for Collins' vaults. Lem is reluctant to go, but Collins' pretty niece Rose changes his mind. In Chicago, Lem finds a great deal of criminal activity, but none of it can get the best of him.
