Mustang Pete receives a letter from his daughter, Sophie, who is away at boarding school, asking permission to bring some girls home with her to spend their vacation. Mustang flatly refuses. That afternoon he and Slippery Slim have a fight over a checker game, and to get "square" Slim advertises the fact that he will pay his ranch hands double the salary that Mustang will pay. As a result Slim gets all of Mustang's helpers. Mustang then writes to Sophie and tells her to bring home the girls if she cares to. The girls arrive the following day and Mustang has an abundance of help, all of Slim's helpers deserting him.
