Betty Gordon in the Land of Oil

Betty Gordon and Bob Henderson depart for Oklahoma—Betty, to see her Uncle Dick, and Bob, in hope of finding his aunts, the Saunders sisters. During the train journey, Bob overhears two sharpers discussing how they can cheat old women out of their farms in Oklahoma and make a killing in oil. To Bob's surprise, he hears the men mention the Saunders sisters. Bob wonders whether the men could be speaking of his aunts. In Oklahoma, Betty and Bob take a great interest in the oil industry and visit the oil fields with Uncle Dick. One day, Betty's horse runs away with her, and Betty stumbles onto the Saunders farm! Betty discovers that Bob's aunts are ill and in dire need of medical attention. Betty summons a doctor, and Betty and Bob stay with the women while they recover. Soon, the two sharpers arrive at the Saunders farm and ask to speak to the old ladies. Betty and Bob tell the men that the Saunders sisters are ill and unable to have visitors. The men leave, but later, Bob disappears! Betty is certain that the men are responsible for Bob's disappearance, and she hopes that she can find Bob before the men force Bob's aunts to sell their farm.
