Deputy Marshal Ken Maynard heads off to Oklahoma where a gang of nasty cattle rustlers is terrorizing the local ranchers. After a bit of detective work -- greatly aided by a motley group of would-be outlaws deputized for the occasion -- Maynard can unmask supposedly upstanding citizen Tom Santschi as the leader of the rustlers. Maynard was hitting his stride with this fine Western produced by Charles R. Rogers for First National. Rotund Mexican actor Chris-Pin Martin, later familiar to moviegoers as The Cisco Kid's sidekick, appeared in this film under his real name, King Martin.
