Anne, a boardinghouse worker in New York's tenement district and an inveterate daydreamer, is rescued from the abuse of neighborhood hoodlums by Wellington Kingston, a society man who returns her to Mrs. Finney's boardinghouse in his Rolls-Royce. When she is goaded by a drunken guest into attending a society ball, Kingston relieves her embarrassment by introducing her as Princess Anne, visiting incognita; but Madeline Sheivers, angling for Kingston, maliciously exposes Anne. Mrs. Finney, enraged by her associating with the rich, turns her out; she accepts a cafe job, leaves it when a customer makes unwelcome advances, and becomes a model at the Fifth Avenue establishment of Theodore Chappell, who is tiring of the attentions of Madeline. Anne stays over at Rebecca Morgan's apartment and invites Kingston to dinner; making his departure, he sees Madeline shoot Chappell. Anne tries to assume the guilt, but Johnny, a cabdriver friend, convinces the police of Madeline's guilt. Kingston and Anne are happily united.
