At an international school in Jakarta, a philosophy teacher challenges his class of twenty graduating seniors to choose which ten of them would take shelter underground and reboot the human race in the event of a nuclear apocalypse. When the last day of school comes for a group of students in a philosophy class, their instructor, Mr. Zimit, challenges them to different sorts of exercises that take place in a post-nuclear apocalyptic world. While there, they each get chosen professions and have to decide whether who is valuable or not because the bunker they will be staying in for a year has only enough oxygen for 10 people. Mr. Zimit challenges them in different rounds to see how they could survive. Issues arise when they notice Mr. Zimit is disruptive to the game.
