Summer months in a humble neighborhood of a big city. The narrator and Alber entertain themselves painting vindictive graffittis. The narrator´s role model is his older brother, a lonely boy in love with Sira. At parties, the older brother sings songs by Roberto Carlos, which earns him the mockery of the other boys his age. When, because of a silly bet,  Alber and the narrator must paint a graffiti on the new house of the most respectable man in town, the boy who used to imitate Roberto Carlos will help them.
