Berto is missing, and his classmates Mia, Eric, Samira and Justin at the New York Solfandi music school need to find him to make up a quintet to perform at the Fall Festival. Where can he have gone? Berto is mad about music, so he could have gone anywhere he can listen to it. The friends embark on a frantic search through the city's streets, bars and theatres, where they come across Latin, jazz and classical, rap, gospel and theatre music. With explanations from teacher Yvette to help, you can enjoy the journey as much as they do.
