Through the death of a relative, New York sweatshop worker Lizzie Holt is transformed into Miss Elizabeth Holt, heiress. Elizabeth soon tires, however, of the shallowness of society life and occupies herself by working in a settlement house on the lower East Side. There she falls in love with John Russell, an idealist who despises the rich, and to escape his scorn, she identifies herself as Miss Holt's secretary. John's efforts to close up ward boss Ted Phelan's gambling house next door prove successful when the place is raided, but when several of Elizabeth's acquaintances on a "slumming party" seek her aid in escaping arrest, John discovers her true identity. He is about to change his mind about marrying her, when Elizabeth convinces him that her love and her character are true, and the two are united.
