Since when, a video of a suicide live broadcast has gone viral on the Internet. The most terrifying thing is that everyone who has watched the video has died without exception. One night, Morisaki Noriko, a girl studying at a girls' high school, fell to her death. She happened to have looked for that video on the Internet before her death. Morisaki's homeroom teacher Ayukawa Akane (played by Ishihara Satomi) doubted the rumor. At the same time, the police also investigated the message and found that everyone who had watched the video had died unexpectedly. What is incredible is that even if the video is deleted, it will go viral on the Internet like a virus. In the end, all the blame is pointed at Kashiwada Seiji (played by Yamamoto Yusuke), the initiator of the suicide video. He seems to be summoning a certain evil spirit with strong resentment to appear. What is the truth?
