"All Of Us Are Dead"|Season 1|Episode 10

Cheong-san's cries attract the attention of the nearby zombies, and the rooftop survivors flee. Hyo-ryung falls down while running, and Ji-min leaves her behind. Ji-min gets lost and is killed in the school's football field. Meanwhile, Hyo-ryung is rescued by Woo-jin. Ha-ri, with her companions, reunites with her brother and they met up with the others at the auditorium. Upon entry however, Nam-ra, due to her half-zombified condition, quickly detects a huge zombie horde. During the attack, Min-jae flees outside while Jun-seong sacrifices himself to buy the others time to hide inside the sports equipment room. The next day, the survivors formulate a plan to use the sports equipment and metal carts to form a movable barricade to surround themselves while making their way out of the auditorium. As they carry out the plan, the zombie horde attacks them and Jun-yeong becomes infected. Just as the zombies are about to overwhelm the barricade, the door suddenly opens and On-jo sees her father, who has finally reached the school. Meanwhile, the military and scientists analyze the data in Byeong-chan's laptop, and after the experts predict that the zombie epidemic might endanger the entire country, the military decides to bomb Hyosan.
