Fresh from serving a prison sentence for a crime he didn't commit, scowling cowboy Jim "Trigger" Morton (Ken Maynard) rolls into an Old West community in search of those who framed him. Shortly after arriving, Trigger confronts an outlaw in a saloon, and the citizens rally to make him their sheriff. Now the face of local law enforcement, he finds his quest for vengeance is further complicated when an old friend (Walter Long) turns up with a proposal for a tempting heist.
