For the physics lesson, all the pupils are supposed to come up with a topic for a presentation. Of course, hobby astronomer Emilia doesn't have to think long. Her great passion is black holes. Since the physics teacher finds this topic a little too difficult, he allows Emilia to give a presentation on it if she chooses a partner to work with. Leon, Maurice and Max do everything they can to convince Emilia that they are the ideal partner, because for them this means a guaranteed good grade with minimal effort. In the end, Emilia decides in favour of Max. He learns from Maestro Barenboim in a rather unorthodox way that not only the audible notes make the music, but that pauses and silence are at least as important.
