This film features the horrible realities of tenement housing which was in abundance during the early part of the 20th century. Shocking scenes of death and despair are very evident in the lives of the unfortunate people living in these "rat" holes. Sylvia Sidney is excellent as the crusader fighting against these "buildings of despair" knowing first hand because her own brother became a "victim" of living in these buildings. Leif Erickson is the "rich" landlord "by inheritance" of these "death traps" and joins the battle in tearing them down. The joining of the "poor" and "rich" in the struggle against tenement housing is what makes this film worthwhile to watch. If you are an activist against "injustice" then this is the type of film that will get your "dander" up.
