Independent and aggressive, Boksoon is known around the neighborhood as a psycho bitch because of her weird behavior. She is slow and not very smart due to a developmental disability, but is nonetheless a brave young woman with a happy inner world. Boksoon manages to make a living by running a street stall at the local market with her younger sister Eunjeong, whom she loves more than life itself. The namecalling doesnt affect her at all, and she only cares about working hard and saving up money for Eunjeongs education. Their relatively peaceful life is disrupted when Taesoo, who lives alone in a deserted forest, kills Boksoons beloved sister because Eunjeong may have stumbled upon the truth of his murderous lifestyle. Boksoon is completely consumed by her grief, madness and uncontrollable rage. Despite her limited mental ability, she begins planning her revenge, and joins up with Nari, another girl who is being chased by Taesoo. Taesoo is a merciless, unpredictable serial killer who commits brutal murders for no reason, then methodically covers up his tracks. He cares deeply for his adoptive family, stepmother Kyeongja and older brother Iksang, who took him in as a young boy. But it was his familys opportunistic attitude to exploit Taesoo despite their disgust and fear towards him that only aggravated the loneliness and monstrosity within him. Eventually, Kyeongja and Iksang secretly bring in some gangsters in an attempt to kill Taesoo. With his animalistic senses, Taesoo escapes death, but ends up getting terribly injured. Boksoon finds Taesoo just then, and a deadly battle unfolds between this frail but strong young woman and the bemused, ruthless killer that ruined her life.
