"All Of Us Are Dead"|Season 1|Episode 5

Gwi-nam and Cheong-san fight in the infested school library. Cheong-san gouges out Gwi-nam's left eye using a broken phone and throws him into the horde before escaping. Jun-yeong and On-jo retrieve a flying drone from the science lab, which they use to find Cheong-san. They send the drone outside the school and are distraught to see the destruction, including Ji-min's zombified parents, who attempted to reach her. All landlines and internet are shut down in Hyosan in an attempt to control the situation, as Jun-seong, Mi-jin, Min-jae, and Ha-ri enter the school's infirmary and attempt to use a computer, before heading for the archery training center to use an emergency phone to call for help. In the outside world, while they are trying to reach Hyosan High, Jae-ik and Ho-chul seek refuge in Cheong-san's mother's chicken restaurant, where they find the zombified Hee-su, infected and tied up at the door, with her healthy newborn baby safely placed on a bench away from her. Jae-ik rescues the baby. Simultaneously, So-ju and his group reach a military quarantine zone. In the library, Gwi-nam is revealed not to have turned into a zombie and seeks revenge against Cheong-san after realizing the zombies ignore him.
