A cruel death game to determine the one and only final survivor.
On an ordinary day, eight students attending Jeongan High School are kidnapped by unidentified individuals.
They wake up in an old, abandoned school completely cut off from the outside world. Soon after, a broadcast rings out, announcing that this is the stage for a death game that will leave only one final survivor.
At first, no one can believe this reality. Even amidst fear and confusion, they comfort and rely on each other, searching for a way to survive together. However, as survival choices pile up and unexpected events occur, their once ordinary relationships slowly begin to crumble.
People they trusted because they were friends, people they protected because they were precious. Now they are placed in a situation where they must suspect and be wary of each other.
A closed school where friendship and betrayal, trust and suspicion are intertwined.
Who will you trust? And will you be able to survive until the end?

A faint fluorescent light flickers.
As you open your eyes, a strange ceiling and the scenery of an old classroom enter your vision. Desks covered in dust, cracked windows, and a tightly locked entrance door. Your last memory is not clear.
Familiar faces are around you. Ryu Geon, Yeon Woojin, Kwon Jaeyoon, Choi Ian, Kang Yewon, Han Seoyun, and Oh Harin. The seven people you faced every day in the same class are also looking around with confused expressions, not knowing what is going on.
Yeon Woojin spoke up with an awkward smile. Choi Ian was checking on the condition of the others, and Kang Yewon tried to calmly assess the situation. Han Seoyun looked around anxiously, while Kwon Jaeyoon was examining the tightly closed door.
Static— Bzzzt.
Noise flowed from the speaker attached to the classroom ceiling. Soon, a mechanical voice devoid of any emotion echoed through the classroom.
『All participants, wake-up confirmed.』
『From now on, you will participate in a death game that will continue until only one final survivor remains.』
Instantly, the classroom began to stir in commotion.
『The rules of the game are simple. Survive. If necessary, you may eliminate other participants.』
Someone let out a hollow laugh. However, the following broadcast did not allow for any jokes.
『Items necessary for survival and various weapons are hidden inside the school. Additionally, there are shelters and secret spaces not exposed to the outside. Please find and utilize them yourselves.』
『Cooperation and betrayal, escape and pursuit. All choices are free. However, there is only one final survivor.』
The broadcast cut off.
For a moment, no one could move. While thinking that what they just heard couldn't possibly be reality, the tightly locked doors and windows silently proved the situation they were in.
People who were friends until yesterday. Now they have become opponents who could threaten each other's lives.
