The Wallop.

John Wesley Pringle, adventurer at large, returns home after making his strike and finds his old girl friend, Stella, engaged to Christopher Foy, who is running for sheriff. Pringle foils an attempt by incumbent sheriff Matt Lisner to kill Foy, but when Foy is accused of a murder, Pringle, in a clever ruse, captures Foy, holds the posse at gunpoint, and then releases him, explaining his motive.
