The first of the five episodes shows the individual experiences of 500 children and young people, taking part, for the first time, in a national meeting of youth bands during the summer of 2012, in Oaxtepec, Morelos. Most of them had practically no previous musical training. They came from all over the country, from cities that have suffered from crime related violence, from poor rural or Indian communities that lack proper health and infrastructure, from border cities where drug trafficking has destroyed normal social interaction. For many of them, it was the first time they had traveled away from home and had contact with kids from other parts of Mexico.
