Small but tough BAEK Sang-ah is called Miss BAEK. Abused by her alcoholic mother when young, Miss BEAK has learned how to shut others out. One day Miss BAEK comes across a young girl, Ji-eun, victim of domestic violence by her game-junkie father and his girlfriend. Miss BAEK sees Ji-eun as a mirror of herself and slowly opens her mind to Ji-eun and tries to help her out. However in the reality Miss BAEK is just a stranger to Ji-eun who has no right to protect this girl. When Ji-eun finally runs away from despairing violence, Miss BAEK pushes herself to fight for Ji-eun, even if it means risking her own life.
