Outlaws of the Rio Grande

Back Trail is one of the livelier entries in Monogram's Johnny Mack Brown western series. Brown rides into a small town where he becomes embroiled in a blackmail scheme. The town's banker (Ted Adams), a pillar of respectability, once served a jail term. Outlaw leader Pierce Lyden threatens to reveal Adams' secret if the banker doesn't let him know in advance when the gold shipments are going through. Adams tearfully tells Brown the whole story, whereupon Johnny rides shotgun on the next shipment himself. Back Trail was one of the last films directed by workhorse Christy Cabanne, whose career stretched all the way back to the D.W. Griffith days.

Flame of the West has always attracted more attention than most of Johnny Mack Brown's Monogram westerns, if for no other reason than the offbeat casting of Douglass Dumbrille.

When he takes on a gang of crooked gamblers, Nightlander is shot down in cold blood, compelling frontier doctor John Poole (Johnny Mack Brown) to put his Hippocratic oath on the back burner and strap on the shootin' irons.

Their suspicions are confirmed when Renfrew finds the control stick has been jammed, forcing the plane to fly in one direction until the gas ran out. Mine owner Louise Howard (Louise Stanley) reports that her superintendent is missing. The Mounties find him murdered and that too has been made to look like an accident. A new mail service pilot, Bill Shipley (Warren Hull), arrives. He had gone to training school with Renfrew but had been cashiered for misconduct. The Mounties discover that Raymond (Karl Hackett), who had been working for Louise, really owns the flying line managed by Yuke Cardoe (William Pawley.)
