This time the final exam was somewhat strange from the very beginning. Confused names of participants, a crowd of malingerers, disguise scams and more - this is a little unusual, but it does not go beyond the scope of school everyday life. But the Minister of Education killed in the corridor is already a problem. And it needs to be hidden by order of the authorities, who are afraid of bureaucratic red tape in the event of an early completion of the exam. Two young teachers who find a dead minister near their post are forced to take up the investigation because the killer is constantly hunting for someone, and the police really want to find a scapegoat.
