Obdulio is an 11-year-old Afro-Uruguayan boy who lives with his grandmother and sells newspapers for a living while he cannot read or write. Obdulio is not interested in going to school until he finds out that the night watchman of the newspaper's office is a charismatic magical "Maestro" who not only introduces him to the world of literacy but also teaches him the real meaning of life through the lyrics of the "Murgas" (Carnival Pierrots) during the mythical nights of the irreverent and provocative Uruguayan carnival.
