Leave It to Gerry (1924)

Geraldine Brent, a tomboyish girl, is separated from her mother and taken east by wealthy relatives. In her absence, her mother is dispossessed and sent to the poorhouse. "Gerry" learns of this action, unmasks the culprits--mortgage-holder Masters and oilman Colonel Pettijohn, who have discovered that the property is rich in oil--and puts matters aright.
