เด็กมัธยมปลาย 6 คนที่ติดอยู่ในลูปเวลามรณะต้องช่วยกันตามหาชิ้นส่วนร่างกายของศพนิรนามที่กระจัดกระจายอยู่ เพื่อถอนคำสาปและเอาชีวิตรอด
High school student Asuka, at school, sees the apparition of a dead student named Haruka, asking Asuka to find her body. Asuka and her friends attempt to find the eight scattered pieces of Haruka’s corpse in the school, and learn more about the Red Person ghost that took Haruka. The Red Person hunts students who are alone at school to kill them, and until they exit the school gates, the Red Person will keep appearing before them. When the Red Person kills a student, it scatters the student’s body into eight pieces, and tasks another person to find the pieces in the school. If Asuka fails to find Haruka’s body, the day will repeat over and over and she and her friends will keep dying until they do.
