All of Us Are Dead Ep. 1 | Twitch Stream Reaction (Patreon)

A gang of bullies corner Hyosan High student Lee Jin-su on the rooftop of a building. He tries to fight them off, but is pushed off the roof and left hospitalized. He vows revenge against his bullies before suddenly turning into a zombie, prompting his father, Lee Byeong-chan, to smuggle his body home. Several days later, Kim Hyeon-ju, one of Jin-su's bullies, is bitten by an infected hamster in the school's science lab. Byeong-chan, a science teacher at the school, witnesses this and locks her inside the lab. She escapes the next day, though now infected and delirious, and bites school nurse Kim Kyung-mi before being transported to the hospital. Police arrive at the school and arrest Byeong-chan. Shortly after, Kyung-mi turns into a zombie and attacks several students, triggering a viral outbreak within the school.
