After the final exams, a body is found hanging in the men's bathroom, its cause of death uncertain—suicide or murder? With no clear signs of foul play, the investigation uncovers bullying within the class and complex student dynamics. The suspects include a trusted teacher, a class president fighting for justice, a passive gifted student, a weak follower, and a powerful troublemaker. As motives and opportunities are questioned, the mystery of who killed the student unfolds in the near-empty school.
