The Silent Revolution

A pair of pupils from sixth-grade, Theo and Kurt, get their classmates to participate in a silent protest in solidarity the victims of the violent uprising, as a way to commemorate their deaths and the dead of their their Communist soccer hero. They start this memorial at class, leaving the teacher in shock. He doesn't know why why his pupils aren't answering any of his questions, and that makes him really angry. Every action has an equal oposite reaction and in Germany every action has political consequences. They end up being investigated by the headmaster of the school, the Education Board and the Minister of Education himself in order to find answers. They don't understand what exactly is the goal of the protest, but in order to end it they decide to give the entire class a warning. They will have only one week to reveal the person responsible for the idea, or they won't be able to graduate.
