The citizens of a small western town are suspicious of mysterious stranger Dick Alwyn and wonder if he is an escaped bandit. Dick proves his mettle to Dolly, the daughter of a local ranch owner, by rescuing her from a possibly fatal accident, and the couple falls in love. Dick also displays his bravery by breaking a fierce wild horse, but is still threatened with being lynched by an irate mob of townsfolk, who believe that he is a bandit. Dick escapes and captures the real culprit. Upon his return to town, Dick reveals that he is actually a U.S. Deputy Marshal.
