Akif Erdem, the physics teacher who is the protagonist of the story, wants to teach his students a “lesson in humanity”. The only thing is – Akif the teacher uses a different teaching method than the teachers we know and are used to. For their last lesson as a class, Akif Erdem holds the students of his 12A class at the Küçükkuyu high school hostage and separates the class from the rest of the school using a bomb. The students and Akif will no longer be able to leave... and Akif the teacher asks the students a question, “Who one among you caused the death of fellow 12A student Kay Örnek?” There is only one way for the young people who have been taken hostage to get out of this situation: to tell the truth!
