A series of stagecoach holdups have all been marked by a mysterious figure clad in black gives a whistle signal at a certain spot. Johnny Mack Brown arrives in the town to recover his stolen horse, but is asked by stage operator Chet Norman to do what he can to help stop the outlaws. This irks Sheriff Dave Holland who becomes peeved that Johnny is asked to do his job as well as get the attention of Beth Fairchild, who is Dave's sweetheart, as well as Norman's niece. Chief suspect of the black robed figure is banker Claine, who is organizing the outlaws to get the gold shipments that are arriving, while one of his henchmen, Slade, is secretly plotting to get rid of Claine after they made their big strike. Johnny and Dave need to settle their differences to get stop the outlaws and find the identity of the mystery rider. One would think towards the end of Johnny's career his films would be getting weaker and weaker, but this film proves it is farther than the truth, basically helped by a well written script with good action and excellent plot twists. Despite not seeing eye to eye during the film, Brown & Ellison make for a good team and make me want to check out their other team ups. Worth a good look. Rating, based on B westerns, 9.
