- Plot: Wellington Holmes, a timid and very shy horticulturist, heads for Big Bluff. When the stagecoach is held up by Buckskin Bill and his men, he coincidentally knocks out three of them earning himself the unwanted job, as Marshal of Big Bluff. After escaping Big Bluff, disguised as a woman, the stagecoach is again held up by Buckskin and he, Elena Montoya and her father are made prisoners. He escapes again and when Buckskin arrives in town he again coincidentally overpowers the criminals. Having been previously masked, Buckskin now claims to be Buckskin's enemy and the residents of Big Bluff believe him. They release him and offer him the reward for leading Wellington to Buckskin's hideout. So Wellington and Elena with the ransom money for her father, but no posse, head out to bring in Buckskin. The law is kept and all of the criminals are successfully captured, brought to the county's prison and are put behind bars.
