Apartment 1303 in the Blue Palace Hiroaka has cheap rent. Why? The building is famous for being haunted by ghosts. Not really. The reason the rent is cheap is because it is far away from the train station. At least that is the story given by the Maple Housing real estate agent to Sayaka Imōto who is moving to her first apartment away from older sister Mariko (Noriko Nakagoshi) and their mother (Naoko Otani). All seems well Sayaka’s house-warming party until she leaps off her thirteenth floor balcony. Sayaka’s mother is devastated by the death and in an effort to prevent her from sliding into madness Mariko decides to investigate. She soon uncovers a history of suicides connected to the apartment stretching back to a tragic relationship which exerts a supernatural influence. Does a creepy little girl know more than she is letting on.
