The video intervention project in the neighbourhood of Can Serra (L'Hospitalet de Llobregat) was carried out from January to March 1978. At its origin is the Projecte inicial d'estudi de les formes de vida i cultura popular als barris de Barcelona, of November 1977, written by Video-Nou and promoted by the Fundació Serveis de Cultura Popular. Four videos were made as part of the same project: Qué viene el metro, Història urbanística, Escuela de adultos and El barrio de las fiestas.

The extension of the metro line dangerously affected the structure of some houses. The footage of those affected and the damage caused was presented at the residents' assembly, in the neighbourhood bar and square, and they organised themselves collectively in protest actions. Video-Nou's intervention in Can Serra was the first attempt to use video as an instrument of dynamisation in community life in our country.
