A group of troubled students, including Jong Sik, Chuli, and Hina, are sent to a special school on a remote island. The school is run by strict and abusive teachers, and the students are subjected to harsh rules and mistreatment. A rabid pig escapes and infects the school's principal, who becomes a zombie. The students soon discover that the island has a dark history of burying infected pigs alive, which have now turned into zombie pigs. The students must fight for survival as the zombie outbreak spreads, and they try to find a way to escape the island. In the end, only one student, Jong Sik, survives and escapes, but not before discovering that his friends have become zombies. He takes one of his zombie friends, Chuli, with him, hoping to find a cure, but this decision may lead to further chaos and destruction.
