Doris Wynne, at boarding school in France, is hardly acquainted with her mother, most of the dealings between them handled by a firm of lawyers. So when she falls in love with the brother of a schoolmate, she obtains her mother's consent through the attorneys. Alys Wynne's reasons for seeing so little of her daughter are that she is the companion in crime of "Python" Grant, international swindler. Having ruined a young nobleman and causing him to commit suicide, the pair escape to America. Doris, the daughter, in the meantime, is happily married to Keith Bourne, a young American. An uncle leaves him a million dollars and they decide to return to the United States. Grant and Alys discover Keith and cultivate him. That he is the husband of Doris is unknown to the mother, who is still young and beautiful herself. Grant pretends to abuse his wife and Keith comforts her. A suit for alienation of affection is the result.
