Nozaki (Okada Junichi) is a supernatural novelist. One day, a man named Tahara Hideki (Tsumabuki Satoshi) found him and said that there were supernatural phenomena in his home. He suspected that there was an evil spirit trying to hurt his wife Kana (Kuroki Hana) and child Chisa. So Nozaki found his girlfriend Higa Makoto (Komatsu Nana), who has strong psychic abilities, to investigate the incident together. What the two did not expect was that it was not long before the news of the tragic death of Hideki and Kana came. Various clues pointed out that the "things" lurking in their home were not ordinary people. Realizing that her own strength was far from enough, Makoto moved out her sister Kotoko (Matsu Takako), who was a world-famous exorcist. After a brief investigation of the crime scene, Kotoko invited psychics from all over the world to gather here on Christmas Eve to deal with this unimaginable evil together.
