When Charles King and Bud Osborne are released from prison they've got some unfinished business to attend to, namely US Marshal Buck Jones. Buck only escapes wounded from a blazing cabin fire by the grace of God and the trustiness of his steed Silver. It's why cowboys love their horses.
But what these two geniuses do is put the Rough Riders on their trail as King and Osborne join saloon owner Tris Coffin in a scheme to extort a partnership from freight line owner Dave O'Brien. With Buck Jones out of action for a bit Tim McCoy and Raymond Hatton start their own investigation and decide to play a long to see what Coffin is up to as he seems like the brains. In fact when Jones arrives he nearly kills his companion's scheme.
Forbidden Trails again with a title that makes no sense to the story, the hallmark of the B western is a fast moving western with a bit more plot than normal in one of these type films. Fans of the B western and the stars will like it.
