Bounus is about a conscientious and hardworking math teacher who faces an uncomfortable situation. During the exams, one of his students gets a failing grade and this causes tension between the teacher and the student. However, the teacher cannot change the grade due to his principles and fairness. Due to the teacher's hatred for the student, he decides to put his job position at risk by staging a work. He's looking for a way to show Ali, his student, that he's interested in his job, but he can't change his grade. In this situation, the math teacher has two options: either to end this whole issue by paying the ransom to Ali and accept being guilty, or to use another method to prove himself and keep his position.
