Intro
EPISODE 1 – THE FIRST DAY
The morning starts normally as Ohee arrives at Hyosan High School for her first day. She feels nervous about transferring to a new school and struggles to find her classroom.
While walking through the hallway, she notices a group of students surrounding Beom-seok. Jae-min and his friends are bullying him, laughing as they push him around. Most students ignore it, afraid to get involved.
Suddenly, Su-ho steps in.
"Leave him alone."
A fight almost breaks out, but Jae-min backs away after seeing Su-ho's confidence. Watching from a distance is Si-eun, who quietly returns to his classroom without saying a word.
Later, Ohee meets Yuna, a friendly girl who offers to show her around the school. The two quickly become friends.
During science class, Mr. Kim seems stressed and distracted. Hidden inside the laboratory is a strange infected rat that escaped from an experiment. Nobody notices it crawling under the desks.
After school, Dae-hyun films students for a video project while Seo-jun finishes soccer practice. Everything seems normal until a loud scream echoes from the science building.
Students rush outside.
A student stumbles into the courtyard, covered in blood. Everyone freezes.
The student suddenly attacks another student.
Panic spreads.
Within minutes, more students begin acting violently. Screams fill the school. Teachers try to control the situation, but the infection spreads too quickly.
Ohee grabs Yuna's hand and runs.
In the chaos, Si-eun, Su-ho, Beom-seok, Ji-woo, Ha-neul, Eun-seo, and several others end up trapped inside a classroom on the third floor.
The group pushes desks against the door as pounding noises grow louder.
BANG.
BANG.
BANG.
The zombies are outside.
Everyone holds their breath.
Then the classroom door begins to crack.
The episode ends with Ohee staring at the door in terror as a zombie hand breaks through the wood.
