A 1938 American Western directed by Lesley Selander and starring Douglass Dumbrille, Sidney Toler, and Russell Hayden. Based on the 1921 novel The Mysterious Rider by Zane Gray, it is about a notorious outlaw who returns to the ranch he once owned and takes a job disguised as a ranch hand. Unrecognized by the ranch's current owner, he waits patiently for an opportunity to expose the men who murdered his partner twenty years ago, framed him for the crime, and then stole his ranch. The film was later released for television in the United States as Mark of the Avenger.
