The public high school named Manuel Mujica Lainez is located in Villa Lugano, on the margins of the City of Buenos Aires, where the highest poverty rates are found. During a whole year, a school workshop was filmed on a day to day basis, where 17 year old teenagers worked on the collective mapping of their neighbourhood. With a thorough filming device upon this school assignment, classroom life takes shape and, at the same time, the external social issues lived by the students arise.
