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.—James Hake
