I do not know since when, a live video of suicide has gone viral on the Internet, and the most terrifying thing is that everyone who has seen the video has died. One night, Moriko Morizaki, a girl who was studying in a girls' high school, fell to her death. She was looking for the video on the Internet before she died. Morisaki's grade teacher Nian Chuanqian (Rimei Ishihara) is suspicious of the rumors. At the same time, the police also investigated the message and found that all the people who had seen the video died accidentally. It is inconceivable that even if the video is deleted, it will go viral on the Internet. In the end, all the blame is directed at the initiator of the suicide video, Seiji Takada (Hiroshi Yamamoto). He seems to be using this to summon some evil spirit with strong resentment to appear. What is the truth?
