"Peter Punk" tells the adventures and misadventures of Peter, a Rock & Roll loving boy who has created a small garage band, the Rock Bones, with Seba on drums and Mateo on the guitar. His friend Iván acts as their manager. The only girl in the gang is a sound engineer who has a crush on Peter. Peter's family, however, belongs to the Punk crowd, starting with his grandfather, his brothers, his parents and even the family business, the Central Punk, a store that sells Punk apparel and props. On the same street he has the Central Pop store, selling Pop apparel and props, and it is the Twin Pop's headquarters. The twins are the Rock Bones' arch-enemies and rivals. Peter wants the Rock Bones to become the most popular Rock & Roll band, even though his own peculiar family and neighbors may make it a little harder for him.
