Whispering Corridors (1998)

Synopsis:
The film begins with Mrs. Park, a teacher at the all-girl school, finding something disturbing in a yearbook. She then runs frantically through the hallways, scared out of her wits, before she calls Eun-young and mysteriously tells her that Jin-ju is still around, still attending the school. She then drops the phone and is strangled to death by an unseen person wearing the school uniform.
