After the last train drove to Busan, the zombie virus broke out across the country in an instant. Four years later, the zombie virus was everywhere in South Korea, which was isolated from the world and turned into a dead city. The few survivors boarded the last refugee ship and left the Korean Peninsula abandoned by the world. Veteran Zheng Xi (played by Jiang Dongyuan) and his family were fortunate to board the refugee ship, but as soon as they got on the ship, they found zombies lurking. Fortunately, they were taken in by Hong Kong, and this group of Korean talents were able to go ashore and start a new life in Hong Kong as "Peninsula refugees". But Zheng Xi couldn't resist the temptation of money and joined an action to steal a huge amount of US dollars back home. He and his teammates returned to South Korea and found that there were still a group of people who were not infected with the zombie virus struggling to survive. Zheng Xi decided to take this group of survivors to escape. Can they finally successfully escape from the zombie-killing peninsula?
