Saki Nakamura, a quiet high school girl with anxiety, is bullied by five classmates—Ayumi Tanaka, Riku Shimizu, Haruna Sato, Kenta Yoshida, Mika Kawahara, and her (ex) friend Rina Masu—until she takes her life. After her fate ends, the bullies discover an abandoned website on a computer, where they find disturbing videos of Saki. From that point on, they're plagued by strange, unexplainable things. During a sleepover, they all go to bed and wake up in a creepy mansion. Will they make it out?
