John Wayne and a couple of reasonable action scenes are about all that keep this B-Western afloat. The plot is mildly interesting, with Wayne working undercover trying to break up a counterfeiting ring. But it strains credibility a little too often, and the goofy medicine show settings, while occasionally amusing, cause at least one too many groans. The action scenes are OK, thanks to Wayne and Yakima Canutt, who plays the bad guy. Wayne was still progressing as an actor himself, and would later have much more of a screen presence, but he was obviously above most of the material in this movie. The film itself is really only interesting because he was in it, and it gives you reason to be thankful that eventually he was given a chance to move on to better things.
