Jane Dwight possesses an overactive imagination and spins romantic tales in which she is the heroine. When oil is discovered on her father's farm, young millionaire James Thornton comes to purchase the land, is attracted to the tomboyish Jane, and offers to send the girl to boarding school. A year later, Jane returns home from school posing as a grand dame, hoping to please Thornton. But Jane's airs have the reverse effect because Thornton is disappointed in the change that has come over the tomboy he once knew. Consequently, Jane dons her calico dress and hides in Thornton's car. Upon discovering his tomboy once again, Thornton orders his chauffeur to drive to the nearest justice of the peace.
