When a gang of outlaws starts hijacking freight wagons and then ransoming them back to their owners, government agent Steve Langtry (Charles Starrett) is sent to investigate.  He both goes undercover as an inexperienced traveler and as the masked Durango Kid.  As always, he is accompanied by Smiley Burnette.  In this installment, Smiley tries to invent a machine that can find silver and he also sings a few songs.  His backing band, The Lone Star Cowboys, follow him everywhere that he goes but they don’t actually get involved in the action.

This is another Durango Kid movie, with all of the usual horse chases and shootouts.  The same action montage that started Phantom Valley also starts this movie.  As always, Charles Starrett is convincing when riding a horse or shooting a gun.

What sets this Durango Kid movie apart from the others is the main villain.  Dr. Middleton (played by a regular member of the Durango Kid stock company, Fred F. Sears) appears to be a kindly man who serves as a middleman between the citizens and the outlaws.  Actually, he is working with the outlaws and receives a commission of every ransom that he negotiates.  The reason he can get away with it is because he’s drugged the Sheriff (George Cheseboro)!  He attempts to drug Durango too but luckily, Smiley drinks the water instead.

While it won’t convert anyone who isn’t already a fan of the genre or the character, this is another entertaining outing for the Durango Kid.
