Rin Tin Tin is hunted by ranchers as a dangerous wolf until a prospector befriends him. In this stirring adventure Rinty escapes danger by wearing a disguise and then helps his new master out of a jam too. A dog in disguise may seem far-fetched, but this was no ordinary dog. Rin Tin Tin, Warner Brothers' biggest box office star in the late Twenties, was reputed to be a better actor than many of his human co-stars. He did get top billing.
