Rüpel
A new pupil has joined the seventh grade and - as is often the case - is met with scepticism. What is more: Mathias' classmates are angry because he is frequently late, goes home early and, on top of it, performs badly at school. They have to acknowledge, however; that he is very gutsy. This proves especially true when it becomes a question of passing a dangerous test: who can hold out longest in the ice cellar?
