Jeanette Browning overhears Silas Stone, an aged Wall Street wolf, demanding her as his wife in payment for saving her father from financial ruin. Upon her acceptance of Stone's proposal, her father receives a check to cover his shortage. She then conceives of a plan to make Stone break their engagement so that she can sue him for breach of promise. Stone is invited to the mountains to visit the Brownings, and Jeanette pairs her youthful strength against the old man's advanced age. After tiring him out with dances, midnight suppers, swims and horseback riding, Jeanette plays her trump card when she introduces Stone to her brother Larry, the shame of the family because of his insanity which she claims to have inherited as well. Horrified, Stone attempts to steal away but is caught by Larry. Jeanette feigns despair at the loss of his love and threatens to sue for breach of promise. After Stone patches her broken heart with a check for $100,000, Jeanette confesses to her father that "brother Larry" is actually her sweetheart whom she pressed into service to frustrate the crafty old man.
Jeanette Browning returns from a party bids her escort good-bye at the door, and as she passes through the hallway, overhears loud talk in her father's library. Listening, she hears Silas Stone, a Wall Street wolf, demanding her as his wife as a price for saving her father from financial ruin. Jeanette walks with unconcern into the room, greets the men with a proposal of marriage. When Jeanette leaves the room Stone and the father agree to keep secret the conversation which preceded Jeanette's appearance. Jeanette assumes to totally disregard the difference in their ages. Stone is invited to the mountains to spend a holiday at the Browning cottage. She puts her youthful vivacity and energy against the old man's age. On the principle that the way to a man's heart is through his stomach she feeds him with utter disregard for the fact that he cannot manage the quality or quantity of food of a younger person. She invites Stone to meet her twin brother Larry, whom, she says, has been disinherited by father as the result of his escapades but to whom she remained loyal. Larry meets the couple late at night in the library. Jeanette paints Larry's misdeeds in glowing color and insists that Stone be with her when she meets him secretly. Jeanette reveals to Stone that she, too, inherits the trait which has caused Larry's downfall, but that she has been able, up to the present, to control it to such an extent that it has kept her from disgrace. Stone sickens of his bargain. He attempts to steal away but is caught by Larry. He begs to be freed of his promise to marry the girl, but she refuses. She insists upon a financial settlement to reimburse her for the disgrace of having been jilted. Stone readily signs the check. Then Jeanette confesses to her father. Brother Larry is her lover, whom she has pressed into service to frustrate the crafty old lover.
