An important customer at Armande's, where Iva Seldon works as a model, is Billy Ravensworth, who purchases expensive gowns for a heartless vampire named Rita Challoner. When Billy pays for a number of gowns with a bad check, Iva is sent to Rita's home to collect the finery, and there she meets Bertrand Seldon, whom she recognizes as her own father, a society man who had deserted his wife years earlier and never acknowledged Iva. Rita learns that Billy is poor and breaks off their affair, after which Iva persuades him to pose as her fiancé so that she might enter society. Billy is content to maintain the masquerade in exchange for Iva's money, but soon finds himself jealous over her apparent romance with Bertrand. Iva agrees to accompany Bertrand on a drive, but the car plunges down a cliff, whereupon she reveals her identity. Before his death, Bertrand at last recognizes his daughter, and with his fortune, she and Billy begin a new life.

Because of his poetic name, Caroline becomes involved with Reginald Van Alden, a married fortune-seeker. On the morning of the wedding, she abandons her old sweetheart, Bob Worth, to take a ride with Reginald, but when he takes her to a disreputable roadhouse, she escapes and then tries to commit suicide by drinking cologne.
