In a small frontier town, the ranchers and the farmers are nearly at war with each other.  Cattle are being rustled.  The head of the farmers (Karl Hackett) is accused of killing a ranch hand.  Store owner Fuzzy Q. Jones (Al St. John) suspects that it’s all a set-up and he’s not going to stand for it.  If the farmers kill all the ranchers and the ranchers kill all the farmers, there won’t be anyone left to shop at his store.  Fuzzy calls in his friend, Billy Carson (Buster Crabbe).

Buster Crabbe may have gotten his start in the westerns by playing Billy the Kid but the producers of his films eventually realized that there was only so long that Buster could play a character known as “the Kid” and Billy the Kid’s reputation as an outlaw was actually not helpful at the box office because parents didn’t want to send their kids to a matinee that might teach them the wrong lessons.  After a handful of “Billy the Kid” films, Buster’s western hero suddenly had a new name.  Billy Carson was a standard western do-gooder, called in whenever a town needed to be cleaned up or his old sidekick Fuzzy needed some help around the store.  Crabbe was a convincing hero no matter what but the Billy Carson films lacked the thing that made the Billy the Kid films interesting.  Usually, no one was trying to arrest Billy Carson.

Oath of Vengeance isn’t bad, at least not by the standards of Poverty Row westerns.  There’s plenty of fights and Crabbe, being a former Olympian, looks convincing with he throws a punch.  The plot is a pretty standard B-western plot but Crabbe’s natural likability carries the day.  Fans of the genre will be happy to see Charles King and Kermit Maynard, playing bad guys.  Frank Ellis plays the ranch hand whose murder sets off the story.  It’s always good to see the old gang back together again.
