Fuzzy's niece is killed in a stagecoach hold-up in this "Billy Carson" Western series entry starring Larry "Buster" Crabbe and Al St. John. Billy and Fuzzy quickly learn that the culprit, who not only killed all the passengers but also absconded with $40,000, may be holed up in lawless Pecos City. Teaming up with Roxy (Patti McCarty), a disgruntled singer at Grant Barlow's (I. Stanford Jolley) saloon, the heroes begin an investigation that leads straight to Ed Sperling (Karl Hackett), who claims that he was forced to join in the holdup.
