The plot will go back to 2006, when the White House discovered that the president's confidential documents were hacked and summoned a team of agents led by Leon. During the search, there was a sudden power outage and they were attacked by zombies. On the other hand, Claire, an employee of TerraSave, received a painting that looked like someone was infected with a virus from a teenager with aphasia while supporting refugees in a certain country, and used it as a basis for investigation. The next day, Claire went to the White House to discuss the issue of building welfare facilities, and met Leon by chance and showed him the boy's painting. Although Leon believed that the zombie incident in the White House was related to the strange painting, Claire held the opposite opinion and left. The zombie incidents that broke out in two distant countries will eventually develop into a situation that shakes the country.
