When the story begins, a group of thugs are trying to sneak a herd of cattle from Texas into the territory. This is a problem because there's been an outbreak of Texas Cattle Fever (caused by ticks on the cows). The sheriff's sister catches them...and they disarm her and take her prisoner. It's a good thing Gene and his friends are nearby, as they come to her rescue and hold the crooks for the sheriff. So far, the story is interesting...but then the dopey sheriff just lets the crooks go and tells them they'll have to pay a fine! Now remember....they took the sheriff's sister hostage...yet he just lets them go. No, he's not a crooked lawman...just a dumb one!
Later, the evil man who is OBVIOUSLY behind all this has the sheriff killed. Soon the guy is running a crooked campaign and he drives off the candidate running for sheriff. What's next? See the film.
This is a modestly enjoyable B-western. It doesn't always make sense but it's well made and the story involving. Not among Gene Autry's best...but still pretty good.
