Roma Wycliffe, a high-spirited girl bored with the lavender-and-old-lace atmosphere of her Aunt Henrietta's estate, discovers that her grandmother was a gypsy and decides to become one herself. Wearing gypsy clothing, she runs away to New York, where she is arrested on the suspicion that she is Gypsy Nan, a thief. Mrs. Roberts, whose poodle had attracted Roma's attention, intercedes for the girl and, promising to care for her, takes her to her lavish home. Young John Roberts falls in love with Roma, but the "gypsy" imagines him too stodgy. To win her love, John declares himself the leader of a band of gypsy thieves and then hires a gang of ruffians to prove his claim. When the thugs actually rob a bank, John has them arrested, and Roma, realizing the darker side of gypsy life, marries John.
