Following the outbreak, the whole country of Japan is being evacuated. A volunteer rescue team finishes a final check for survivors in the city and assists in escorting a bus of survivors to a military checkpoint. 

The team is then tasked with assisting in defending a large cruise ship which is the only remaining evacuation transport. The team manages to hold off a massive swarm by destroying a large fuel facility that acts as a wall of fire and manages to reach the cruise ship in time as it departs Japan. 

However, some of the infected have gotten aboard due to poor and rushed screening operations, causing the ship to be in danger of being overrun as the infection spreads. The team assists the military in repelling and ultimately eliminating the infected from the ship. Though they have abandoned their country, the team hold hope that they will one day return to reclaim their land.
