Gyeong-su suddenly transforms and attacks Cheong-san, throwing himself out of a window in the process. Nam-ra reveals that Na-yeon caused Gyeong-su's infection by using her handkerchief smeared with zombie blood to touch Gyeong-su's scratch. The group condemns Na-yeon, causing her to storm out into the halls, with Ms. Park following her. Meanwhile, Gwi-nam betrays several survivors to zombies to escape the kitchen. Cheong-san's mother heads to the school to search for her son. Elsewhere, firefighter and On-jo's father, Nam So-ju, along with his crew, assemblywoman Park Eun-hee, and other government officials are trapped inside a government building. Park Hee-su, a pregnant student, gives birth in a public bathroom stall.

This proved ineffective, however, as Jin-su turned into a zombie and infected his mother as well. Suddenly, a horde of zombies swarms the police station. Byeong-chan, who is bitten, informs Jae-ik that his research on a cure is on his laptop in the school's science lab. He sacrifices himself to the horde, allowing Jae-ik and rookie officer Jeon Ho-chul to escape. At the school, Su-hyeok and Cheong-san retrieve a smartphone from the staff room and encounter Min Eun-ji, a school outcast who was bitten but has not turned.

Cheong-san, who is responsible for Gwi-nam's infection, argues that Nam-ra is infected, but she remains human and does not turn. On-jo suggests that she, Gwi-nam, and Eun-ji developed a form of immunity to the virus. Unbeknownst to them, Na-yeon is hiding inside a nearby locked storage room stocked with food.

Nam-ra's infection grants her incredible strength, allowing her to throw Gwi-nam down the stairs.

Cheong-san reveals his feelings for On-jo, which upsets her. Jae-ik and Orangibberish are rescued by Ho-chul, who returns with a bus and the two children. They are found and evacuated by the military, who also evacuate Eun-ji. Flashbacks reveal that Ms. Park was bit while saving Na-yeon, who now seeks to atone for her actions. She stocks up on food to give to the group and makes her way to the rooftop, but is found and killed by Gwi-nam, who plots another attack on the students.
9	"Episode 9"	January 28, 2022 (2022-01-28)
Gwi-nam climbs to the rooftop and attacks the students, but Nam-ra's strength allows her to overpower him once more, pushing him off the roof. Jae-ik reveals to the military that Byeong-chan's laptop, believed to contain the cure, is located at the school. A dispatch team goes to retrieve the laptop and prepares to rescue the students. However, Eun-ji goes berserk at the encampment and bites Cheol-soo. She is promptly captured and examined, resulting in sudden orders to classify all survivors as asymptomatic; ergo, the dispatch team is forced to abandon the students, much to the students' dismay. A loud thunderstorm ensues, hampering the zombies' ability to hear and smell. Both surviving groups at the school decide to use this advantage for another escape. The rooftop group makes their way to the ground floor, where a horrified Cheong-san finds his zombified mother.

The following morning, Cheong-san and On-jo reconcile and promise to discuss their relationship when they reach safety. The students use metal carts to form a mobile barricade to safely reach the gym's back exit. However, Joon-yeong's hand is bitten through a gap in the barricade, and he climbs over it to fend off the zombies before turning. So-ju, finally arriving at the school, comes to their rescue. Meanwhile, researchers deduce that the virus' adaptability and the irreversible state of its victims make a cure impossible. Commander Jin authorizes the bombing of Hyosan.
11	"Episode 11"	January 28, 2022 (2022-01-28)
Escaping the gym, On-jo finally reunites with her father, but the group is forced to flee again from approaching zombies. So-ju diverts the zombies away, sacrificing himself to allow the students to reach a nearby construction site, where they take cover on a scaffold. Gwi-nam presses Min-jae about the group's whereabouts before biting him and leaving him to turn. The military deploys sound-emitting drones to draw zombies from all over the city to select bombing locations, including Hyosan High. As the students attempt another escape, they are ambushed by Gwi-nam, who bites Cheong-san in his left arm. Cheong-san pushes him off the scaffolding, and knowing he will inevitably turn, kisses and embraces On-jo before rushing away to distract the zombies, allowing the others to escape the school safely. He is attacked by Gwi-nam, and the two fight in a final showdown, culminating in Gwi-nam gouging Cheong-san's left eye to fulfill his revenge. The bombs are activated, instantly wiping out thousands of zombies and seemingly killing Cheong-san and Gwi-nam in the explosion. Commander Jin commits suicide out of regret for authorizing the bombings.

On-jo mourns her father and Cheong-san's deaths. The students reach an evacuated neighborhood, where they fight off a horde of zombies that evaded the bombings. Woo-jin is bitten while saving Ha-ri, forcing Nam-ra to kill him after he turns. As they flee, Nam-ra's cravings for human flesh become uncontrollable, and she nearly bites On-jo. Fearing her own impulses, she strays from the group and disappears. The surviving students—On-jo, Su-hyeok, Dae-su, Hyo-ryung, Mi-jin, and Ha-ri—arrive at a military checkpoint and are finally rescued. Four months later, the government lifts martial law in Hyosan but maintains quarantine measures for the survivors in an encampment. Noticing a campfire on the school rooftop from afar, the group sneaks out to investigate. They joyfully reunite with Nam-ra, who appears surprisingly well. She reveals that there are other half-zombie survivors like herself, before leaping off the roof to join them.
