Just returned from college, wealthy Reggie Van Deuzen (Douglas Fairbanks) returns a lost child to her tenement home and meets Agnes (Bessie Love), an innocent who has taken a job as a dancer in Gallagher's saloon. Reggie dons working-class clothes and follows Agnes to Gallagher's, where he is hired as a bouncer. While protecting Agnes from the dishonorable intentions of the saloon's patrons, Reggie incurs the wrath of underworld boss Tony (W. A. Lowery), who, failing in his attempts to have Reggie killed, challenges him to a hand-to-hand fight with Agnes as the prize.
