Brave miner Dan Emory (Robert Ramsey) befriends a mistreated dog (Ranger) in this action-melodrama produced by Robertson-Cole for assembly-line studio FBO. Dan is later injured in a mining accident and sends the faithful pooch for help. But Ranger is in danger from a group of settlers who accuse the dog of mistreating a child (Mary Dow). Ranger, of course, is innocent, and with the assistance of pretty Bessie Lang (Australian starlet Lotus Thompson), manages to save the wounded Dan. But Dan does not have one of his best days and is soon close to being lynched for killing Bessie's father (Clark Comstock). The real culprit, however, is Ranger's former owner, the nasty "Red" Saunders (Eddie Chandler). Everything is cleared up in the final reel when Ranger and Dan save Bessie from the evil Saunders. One of Rin Tin Tin's many competitors, Ranger never achieved the kind of recognition awarded the famous German shepherd.
