Mandy Spragg is a domestic slave, otherwise a servant girl. She spurns the poor, but Cy Whitfield, her fellow-laborer, loves her. The family go off for an auto ride and return to find Mandy in the best chair on the front porch. But indignation fades when she shows them a letter, declaring her to be the sole heiress of her uncle's money. Just what the legacy is they do not know, but legacy suggests a lot of money, and the head of the house not only lends her money to go shopping with but sends her down in the family auto. Done up in a good copy of a fashionable woman, Mandy does not show up so badly, and even the boys, who are courting the daughters of the house, turn traitor and sue for Mandy's hand and fortune. She will have none of that. Poor Cy is in the cold. Then comes a telegram from the lawyer. The total of the fortune is $25. Mandy's new friends vanish and she is put into her old clothes again and set to beating the rug. The operator explains that he had made a mistake in copying and it should be $225,000. Meantime Cy has proposed, been accepted and Mandy holds fast to him.
