Sofia likes music very much and plays the concertina very well. Her father thinks she has a special gift and wants her to play in the school festival. But Sofia is not sure she can overcome her stage fright and play before so many people, and above all, before the critical eye of Napias, the chorus director, who never smiles and always complains that everybody does everything wrong.
