Andreas makes Leonidas's life difficult at school. Leonidas does not react. Petros, Leonidas's deskmate, faces the dilemma: to go against his fear and speak up at the risk of becoming a target himself, or to go against his conscience and remain silent to protect himself. Are these really the only two choices he has? With a small bear on the ceiling, a game on the tablet, and many mice on the horizon, will Petros manage to find another way?
