The sympathetic and calm director of the school begins to change beyond recognition. It transforms into an unpredictable, psychopathic, fear-free psychopath. After one of the excesses, the man falls off the cliff, and the doctors reveal a brain tumor that led to personality change. However, the hero must be accounted for his actions. A dilemma arises, can illness be an excuse for committed crimes? There is more and more uncertainty, confusion and doubt. A phenomenal cinema, which raises the question of how much we are subordinate to our own biology, and how much we consciously follow our own will.
