Sonia Demitri is the daughter of an exiled Russian nobleman, who comes to this country almost penniless, teaches a while, and then, being a lover of books, starts a little second-hand bookstore. Sonia grows to womanhood unaware of her noble birth, she has a great singing voice. In an old Bible which her father treasures, are the documents which will establish her claim to large estates, but her father tells her she will learn it all after his death. David Tryne, living in the same neighborhood, deformed and with a twisted mind, is a remarkable penman and a lover of the beautiful. He forges a letter of recommendation given to one man. The second man uses it and as a result the first man is accused of forgery. The neighbors try to mob Tryne, who takes refuge in the bookstore. Sonia pities his deformities, aids him, and wins his adoration. To the bookstore comes Sutton, a society man, with Kitty Fish, and an impresario. Later, with Schuyler, they all go to hear Sonia sing.
