A female writer (Takeuchi Yuko), who has written everything from light novels for girls to horror stories, has been invited to write short stories for a magazine in the past six months. Her stories are all from personal experiences submitted by readers, and one girl's submission dragged her into an unimaginable abyss of horror. The girl (Hashimoto Ai) once rented an apartment, but she often heard the sound of clothes rubbing against the tatami. The writer followed the map to investigate, and found that not only the girl's room, but also other rooms in the entire apartment had had strange events. She and her writer friend Hiraoka Yoshiaki (Sasaki Kuranosuke), supernatural event enthusiast Misawa Tetsuo (Sakaguchi Kentaro) and her husband Naoto (Takito Kenichi) continued to track down, even across a century of history, and finally found the source of a series of terrorist events that occurred on this land... This film is adapted from the original work "Zanyu" by Ono Fuyumi, the author of "Twelve Kingdoms".
