A normal school day at Hyosan High turns apocalyptic when a science teacher’s failed experiment unleashes a zombie virus. Lee Byeong-chan — a biology teacher haunted by his own son’s suffering as a bullying victim — created the Jonas Virus to make the weak stronger. What it does instead is turn the infected into fast, ravenous killers within minutes. By lunchtime, the school is overrun. The exits are locked. And no one is coming to help.

Trapped inside, a group of Class 2-5 students must survive on their own — Nam On-jo, the resourceful daughter of a firefighter; Cheong-san, her lifelong friend who refuses to stop fighting; Nam-ra, the isolated class president who discovers something unsettling about her own immunity; and Su-hyeok, the reformed troublemaker who turns out to be exactly who you want beside you. Against them: the infected horde, an ever-present military more focused on containment than rescue, and classmate Yoon Gwi-nam — a bully who gets bitten but doesn’t fully turn, becoming a predator more dangerous than any mindless zombie.

📺 Episode Guide

Spoiler-light recaps — enough to remember where you left off, nothing that ruins the ride.

All of Us Are Dead (Season 1) Episode 1 — The Bite
EP 01
The Bite
January 28, 2022
It starts with a bully and a rooftop. Lee Jin-su, the son of science teacher Byeong-chan, gets thrown off a ledge — and doesn’t die the way he should. Inside the school lab, a bitten rat triggers a chain reaction: another student gets infected, Byeong-chan locks her in his office, and within hours the virus is loose. By the time the cafeteria erupts in chaos, Class 2-5 is already cut off — phones confiscated, exits sealed, the school turned into a trap. On-jo, Cheong-san, and Su-hyeok scramble to stay alive as the hallways fill with the people they used to know.

All of Us Are Dead (Season 1) Episode 2 — Barricade
EP 02
Barricade
January 28, 2022
The infected multiply faster than the students can react. On-jo and Cheong-san pull others into a barricaded classroom — building the core survival group that carries the show. Outside, the city starts to fracture: On-jo’s father, firefighter Nam So-ju, is already racing toward the school. The episode establishes the show’s two-track structure: the students fighting inside, and the adults scrambling uselessly outside.

All of Us Are Dead (Season 1) Episode 3 — The Scratch
EP 03
The Scratch
January 28, 2022
The virus swallows the city as martial law is imposed. Inside the classroom, Na-yeon — wealthy, paranoid, and viciously classist — fixates on a scratch on classmate Gyeong-su’s hand and demands he be expelled from the group. The episode is a sharp piece of social commentary wrapped in survival horror: class bias is more dangerous than the zombies just outside the door. The consequences are irreversible and the show doesn’t flinch.

All of Us Are Dead (Season 1) Episode 4 — Dead End
EP 04
Dead End
January 28, 2022
Two students make a desperate run to the teachers’ office for a working phone. Byeong-chan, now arrested, confesses the truth to Detective Song Jae-ik — the Jonas Virus was created to protect his bullied son, an act of grief that destroyed everything. Gwi-nam gets bitten but doesn’t fully turn, establishing the “hambie” concept: something between human and monster, smarter and more hateful than either. His obsession with Cheong-san becomes the show’s most relentless secondary threat.

All of Us Are Dead (Season 1) Episode 5 — The Drone
EP 05
The Drone
January 28, 2022
Cheong-san gets separated. On-jo refuses to give up — using a recovered drone to try to locate him across the overrun school grounds. Meanwhile Gwi-nam takes a knife to the eyeball from Cheong-san in a brutal library brawl and still refuses to die. The episode is mostly forward momentum and escalating stakes, but it contains one of the season’s most viscerally satisfying action sequences in the library fight.

All of Us Are Dead (Season 1) Episode 6 — Half-Turned
EP 06
Half-Turned
January 28, 2022
Nam-ra reveals she was bitten — but hasn’t turned. She’s something in between: stronger, sharper senses, fighting the urge to feed. The group uses sound to draw zombies away and regroup. Nam So-ju breaks out of quarantine to reach his daughter. The music room becomes a brief refuge where the students record messages to their families — a sequence directly echoing the 2014 Sewol ferry tragedy. It’s one of the season’s most quietly devastating moments.

All of Us Are Dead (Season 1) Episode 7 — The Roof
EP 07
The Roof
January 28, 2022
The students execute their most dangerous plan yet — clearing a path to the rooftop using every trick they have. A helicopter passes overhead but doesn’t stop. Detective Jae-ik runs into a setback that nearly ends everything. The episode is tightly paced and emotionally raw, and the rooftop arrival — a moment that should feel like safety — lands somewhere between relief and dread. Getting up was the easy part.

All of Us Are Dead (Season 1) Episode 8 — Bonfire
EP 08
Bonfire
January 28, 2022
Jae-ik’s crew encounters a lone surviving student. Na-yeon, weighted by what she did, forces herself to face her peers. The rooftop becomes a temporary sanctuary where the group sits around a fire and tells each other things they’ve never said out loud — first loves, regrets, the weight of still being alive. Nam-ra says she’s never had a bonfire with friends before. It’s the season’s emotional centerpiece, and the performances here are what elevate this show above straightforward genre fare.

All of Us Are Dead (Season 1) Episode 9 — The Shift
EP 09
The Shift
January 28, 2022
The military’s understanding of the virus shifts when an anomaly surfaces in the quarantine camp. A disturbance changes everything the command structure thought it knew about containment and the infected. A thunderstorm provides cover as the surviving group agrees to keep moving — the school is no longer safe enough to hold. The episode shifts tone toward the final act, pulling the wider political machinery into focus.

All of Us Are Dead (Season 1) Episode 10 — The Auditorium
EP 10
The Auditorium
January 28, 2022
Two groups reunite — and the auditorium immediately becomes a trap. The episode is one of the season’s most relentless action set-pieces, with the show at full throttle: Gwi-nam circling, the infected pressing in from every direction, and Nam-ra’s control slipping. The show’s ensemble is fully assembled here and the expanded group dynamic creates both new bonds and new friction at exactly the right moment.

All of Us Are Dead (Season 1) Episode 11 — The Bombing
EP 11
The Bombing
January 28, 2022
The National Security Council makes the call: Hyosan will be bombed to prevent the virus from spreading beyond city limits. Estimated casualties — roughly 10,000. Evacuation warnings blare but the timeline is brutal. Nam-ra’s hambie impulses spiral toward a breaking point. Gwi-nam finally catches Cheong-san. The episode delivers the season’s most wrenching farewell — Cheong-san’s last choice is to lure the infected away from his friends, and he and Gwi-nam go down together in the flames.

All of Us Are Dead (Season 1) Episode 12 — After
EP 12
After
January 28, 2022
Ash falls like snow on what’s left of Hyosan. The survivors reach the quarantine camp carrying a weight that won’t lift. Four months later, martial law is lifted and On-jo slips over the camp wall to leave offerings at a memorial tree. Then — a fire on the school roof. It was Nam-ra, still in her uniform, healed and purposeful, finding meaning in protecting others like herself. She jumps from the roof and disappears into the night. The finale is both devastatingly conclusive about what was lost and quietly honest about what — and who — remains.

👁️ Social Commentary

All of Us Are Dead works because it earns its deaths. That sounds like a low bar, but in a genre full of disposable side characters and convenient plot armor, the show does something genuinely difficult: it makes you care about a large ensemble of teenagers and then refuses to protect them. The show was released all at once in January 2022 and spent three consecutive weeks at the top of Netflix’s global non-English chart. It watched over 474 million hours in its first month. That kind of reach isn’t accidental. The young cast — almost entirely newcomers — brings a physicality and emotional rawness that no amount of star power could manufacture. These feel like actual teenagers, which makes everything that happens to them land harder than it should.

All of Us Are Dead (Season 1) (2022) — cinematic still

The show’s real subject isn’t zombies. It’s the systems that fail young people — parents who can’t get to them, military command more concerned with optics than rescue, an education system so pressure-cooked that the virus’s origin is literally a father trying to protect his bullied son. Gwi-nam as the season’s primary villain is the most explicit version of this: he’s more dangerous than the infected because he retained his cruelty. The hambie concept is genuinely clever, using partial immunity as a metaphor for what happens when human ugliness survives even catastrophe. Where the show stumbles is pacing — the middle section sags slightly as the survival loop repeats, and the finale is rushed in ways that feel like a production decision rather than a creative one. Woo-jin’s death in particular deserved more space than it gets.

Cho Yi-hyun as Nam-ra is the season’s quiet revelation: a character who begins as a cold outsider and ends the series as something the show has no easy label for — not fully human, not monster, choosing her own meaning in the wreckage. The bonfire scene in Episode 8 is the best single scene of the season and one of the best in recent K-drama, period. Nam-ra saying it’s her first bonfire with friends is a line that shouldn’t hit as hard as it does. It does.
