Beautiful but poor Bo-Ok is sold to Man-Seok who treats her as a sexual partner. As his three sisters maltreat her as well, lonely Bo-Ok endures all odds and difficulties with relying emotionally on innocent and honest servant Cheon-Dong. But Man-Seok misunderstands them and kills Cheon-Dong. As he tries to kill even Bo-Ok, Cheon-Dong's hatred spirit appears to save her and sends Man-Seok's three sisters to hell where they experience sufferings and regret their faults.
