Summer could be so wonderful for Leon if it weren't for the hooligan Pascal. The eleventh-grader has it in for Leon and relieves him of his lunch box, his cap and even his shoes. But Leon is lucky, because Max is just learning from Maestro Barenboim that real listening is something quite different from just listening.

To this end, Maestro Barenboim equips Max with a blindfold so that he can find his way around his surroundings blindly and by listening carefully.
