Jane Carston was to return tomorrow from Ohio, where she had been for the past three years in school, and the ranch was all agog with expectancy and cleanliness. Bob Evans, head cowboy, was most eager and most anxious of the lot. Tomorrow finally became today and Pa had gone to the station in his best linen duster and the buckboard to meet Jane. Finally, in a cloud of dust. Bob discerns them on the brow of the hill. Arriving at the house Jane greets mother with a rousing smack. She was effusive and kind to all the boys, until Bob. Then, was it possible Jane could be shy? Anyway her greeting was different from the rest. Things progress nicely until Bob is asked to mail a letter for Jane to Dr. J.C. Bronner, to whom Jane refers as "her darling old school friend Jack." Jealousy on Bob's part makes him very miserable, but is intensely amusing to Jane. Jane decides to clean up that "nasty messy old bunkhouse." She discovers a caricature of Dr. Jay Bronner on Bob's bunk and it incites her to further increase his jealousy. Jane flirts with Dick, another cowboy, and he promptly falls in love with her. The crowning blow comes to these boys when Jane tells them that Jack, her doctor, is coming out on a visit and shows them a letter from him in which it is inferred that Jane and the doctor would take a little tour of the world. Desperation makes these rivals join forces against this common foe, and they determine by "black hand" means to make him leave the country. The day the doctor is to arrive, all the boys are to go to the round-up and branding, and Bob and Dick both promptly refuse to go to town for the doctor, but all the boys leave the ranch. Jane goes herself and meets a charming young girl, Dr. Jacque Bronner. The girls are convulsed over the anger of the cowboys, but Jane secretly admits to Jacque her love for Bob. Returning from the branding, they are told the doctor has a headache and Jane was serving tea to the doctor in "his" room. This is too much for the boys. That night they enter the doctor's room, masked, with the purpose of "blue-checking'' him out of the country. In the surprise which follows their discovery of the doctor's sex, they miscalculate her determination, and Dick receives a painful but not severe flesh wound from the doctors silver derringer. Doc keeps them covered and yells lustily for help. Discovery and confusion not unmixed with mirth, follows. During convalescence under the Doc's attention, Dick heals his arm and breaks his heart. Bob sees silence may be golden, but learns that a speech in time saves many heartaches. Dick's heart and arm are healed simultaneously.
