Serial murders have recently plagued Inaba, with the police struggling to find any leads. Despite this, due to his parents going abroad for work, Yuu Narukami moves to the small town to live with his uncle for a year. He enrolls at Yasogami High School, where he meets and befriends Yousuke Hanamura, Chie Satonaka, and Yukiko Amagi. While hanging out together after school, the group fills Yuu in on the urban legend known as the "Midnight Channel"—a mysterious TV channel that only appears at midnight on rainy days while the viewer is alone. Curious about the claim, Yuu decides to tune in that night, only to see the next victim of the serial murders appear on the screen instead. He also finds himself being drawn into the TV, which intrigues his newfound friends enough to want to investigate.
