Moon Gyeong-hui

After being appointed as the vice-principal of her alma mater, Eun-hee becomes plagued by hallucinations. Branded a troublemaker by the teachers, Ha-young hears strange sounds coming from the school's dilapidated restroom.

Jeong-in, who recently divorced a violent husband, moves back to her hometown. While suffering from nosy villagers, she is soon drawn to Hye-jung, a newcomer to the town. Two young women soon get closer and Hye-jung’s freewheeling and confident character inspires Jeong-in to break free of her wretched life. One day, Hye-jung suggests Jeong-in share a ‘hobby’ with her, and now their bloody hobby is about to begin.
