The story takes place in a world where zombie attacks have threatened the survival of mankind. As one of the few humans, Krott (Alan Van Sprang) decides to lead his brothers to find mankind's last home. Under the guidance of Elder Patrick O'Flynn (Kenneth Welsh), they learn that there is a pure land on a remote island. However, what Crott does not know is that he and his men are involved in a conspiracy. Only then did Krott discover that there was a new crisis here. They seemed to be involved in the struggle between the Offlin family and their rival Mutons family. It turned out that after the large-scale zombie outbreak, O'Flynn advocated exterminating these monsters that had long lost their humanity. However, Mutons believed that killing these zombies who were once relatives and friends was too cruel, so he confined them and hoped that they would recover.
