Princess Delatorre, young and beautiful widow of an Italian scion of royalty, returns with her fortune to the small American town where she grew up as Ellen Gutherie. Arriving by train a few days earlier than she planned, Ellen is mistaken for Mrs. Arden, a seamstress of doubtful repute from a neighboring town. She carries on the deception for fun when her nearsighted Aunt Katie and others believe she is Mrs. Arden. Phil, her old sweetheart, recognizes her, however, and shows her his new invention, a corkscrew that turns itself--a failure because of prohibition. Ellen leaves, having heard how much store is set on her coming; she returns on the proper train, elaborately made up as Princess Delatorre, and the big reception takes place as planned. Then she and Phil return to Italy, where they expect the corkscrew to be a success.
