The Haunted School (2007)

Original title: Hau mo chu

The Narranmoda Boarding School is strict for girls and has rigid rules of behavior, but the headmaster accepts four male students to improve the income of the school. However, the boys are segregated from the girls and the inspector Miss Fong keeps them under the surveillance of the dedicated monitor student Ho Yat-Man. The urban legend tells that the school is haunted and when students break the school rules, they are called to the director office and vanishes or are found dead.
