Being in the presence of a gun-slinger is intimidating enough, but when a "thundering" gun-slinger comes riding over the horizon, it's time to make out the will and pick the coffin. Buster Crabbe plays Billy Carson, aka Billy the Kid, while Al St. John is his grizzled sidekick Fuzzy Q. Jones. The nephew of a cattle rancher framed for murder, Billy strives to clear his uncle's name and learn the identity of the genuine culprit. Meanwhile he falls in love with Bab Halliday (Frances Gladwin), daughter of another framed cattleman. Al St. John's extended comedy routines are accompanied by a stock musical score that would still be in use in made-for-TV cartoons well into the 1960s.
