 The latest brawl in lawless Prairie Port ends with saloon gambler Turkey (Lane Chandler) shooting town Marshal Bates (Hank Bell). Wild Bill Saunders (Bill Elliott) pursues the killer and brings his dead body back to town, and Coleman (Don Beddoe) appoints Bill as the new Marshal. Outlaws Rawhide (Dick Curtis) and Handy Klemm (James Craig) attempt to rob Pepper Jenkin s sister, Mary (Irene Herndon), as she is driving into town, her team runs away, and Bill and Pepper (Iris Meredith) find her dead under the overturned wagon. Bill serves warrants on two outlaws and town banker Carp Blaisdale (Kenneth MacDonald), secretly head of the lawless element running the town, advises them to submit, planning to terrorize the witnesses at the trial. Mrs. Gardner (Stella LeSaint) informs the court that her husband, a key witness, is so badly beaten that he can not come to testify. Pepper follows Handy and another henchman and sees them silence the witness (Fred Burns) with a bullet. Bill arrives in time to save Pepper from also being silenced. Bill begins to suspect Blaisdale as the ring leader and sets a trap to capture him.
