[Machine Translation] Bonner is a new student who is excited about university life. However, as soon as he enters the dormitory, he is subjected to a humiliating ritual called the "welcome party from hell" hosted by the dorm's self-governing club, Phi UP. Then, his mother tells him about the accident 20 years ago. During the welcome party, a young man named "Sid" accidentally fell into a bathtub filled with sulfuric acid and lost his life. Soon after, something happens to Dan, the club's most violent member, and his body collapses. Then, Sid, who was supposed to have died 20 years ago, emerges from inside the body.
