at SFlix. Perros Callejeros is based on the juvenile delinquency of the 1970s and 80s in Spain. The story is set in Barrio de la Mina in Barcelona one of the most conflict neighbourhoods in Spain. The characters chosen were real juvenile delinquents all with criminal records, which the director used to give the film a realistic touch. This film is very powerful and dramatic, it shows how these kids were brought up to survive on the streets.
