Following the death of their mother, sisters Su-mi and Su-yeon are sent to convalesce in a mental hospital. When they are released, they are greeted by their father and taken home. Once there, it becomes obvious that this isn`t the wholesome family unit that the girls` new step mother wishes it was. On their first night home disturbing and seemingly unexplainable events - footsteps on the stairs, doors opening of their own accord - begin to occur, and strange hallucinations plague the family. It soon becomes impossible to tell whether it is the sisters` unstable mental health, the cruel mind games played by the step mother, or the dark presence of a supernatural force which is at work within the house. Stylish and shocking, this visually arresting tale of family secrets and uncertain realities is based on a traditional Korean folk tale. Guaranteed to have you gasping for breath with each successive scare, you`ll be kept guessing until the very end of this unique and brilliant film.
