Synopsis by Hans J. Wollstein
Clark Stuart (Ray Corrigan) heroically rescues Kit Carson (Sammy McKim) from the burning Presidio, the boy none the worse for wear. Meanwhile, a captured Jim Bowie (Hal Taliaferro) overhears Dupray (LeRoy Mason) and his men discuss how they have trapped the Rider (Julia Thayer) in Box Canyon. It is all a ruse, of course, and Bowie is allowed to escape. Believing that their guardian angel is in danger, Clark and the wagon train crew head for the canyon and ride right into an ambush. Clark manages to escape but his horse loses his footing jumping across a deep gorge.
