Alex , Gaby and Oki are three misunderstood adolescents from lower class living in a big city . They are unadapted and unknown children for their parents , teachers and themselves . Their emotional loneliness and isolation to be led to unexpected and tragic consequences . They are ESO students and at school they have troubles with teachers and partners . Meanwhile , the teens dedicate themselves their hobbies such as Flamenco dancing , Kick-boxing and graffiti on walls . At the end takes place an astounding tragedy . ¨Los Niños Salvajes¨ or ¨Els Nens Salvatges¨ is one of several movies dealing with Spanish adolescence and their particularities such as : rude education , jobless , sex , drugs , and delinquency , all of them interwoven with problematic parents-children relationships . This genre achieved splendor during the 70s and early 80s such as ¨Perros Callejeros I and II¨, ¨Perras Callejeras¨ , ¨ Los Ultimos Golpes Del Torete¨, ¨Yo el Vaquilla¨, mostly realized by Jose Antonio De La Loma , ¨Navajeros , "Colegas", "El Pico 2" by Eloy De La Iglesia and especially ¨Deprisa , Deprisa¨ by Carlos Saura and later ¨La Estanquera De Vallecas ¨ , among others . These films were notorious in the years of the Spanish transition to democracy including provoking and polemic issues and played by unknown young people . Drugs , delinquency, and generational problems are the habitual subjects in these films and specially dedicated to the underworld of heroin and a very realistic look . In "Los Niños Salvajes" or "The Wild Children" there is a similar premise , as some unfortunate as well as hapless teenagers from lower class living hardly in Barcelona streets , then they carry out tiny crimes and misdemeanors and go into a closed mall with unexpected consequences . We see their troubles with teachers and parents , at the same time growing in such streets , slums or "barrio" from Barcelona outskirts and some fine locations . The director creates a sort of Spanish Neo-Realism by tackling the Spanish way of life of a group of teenagers in the streets from a sociological point of view ; being rightly portrayed the city of Barcelona of the 2000s , in the so-called popular neighbourhoods . Filmmaker Patricia Ferreira shows the ugliness of those "barrios" , toughness and cold existence along with some nice kick-boxing scenes . The main cast is pretty well , including young and rookie actors . The support cast is formed by experienced players such as Aina Clotet as Júlia , José Luis García Pérez as Luis , Emma Vilarasau , Merce Pons and Ana Fernández who usually plays for the director .Colorful and evocative cinematography by Sergi Gallardo , being filmed on location in Barcelona and Sevilla . Atmospheric as well as sensitive musical score by Pablo Cervantes , Jose Luis Garci's ordinary . The motion picture was professionally directed by Patricia Ferreira , realizing in realistic style and usual camera movement . Patricia began working in cinema in the 2000s filming shorts and documentary , and has realized a few films , usually Thrillers and Dramas such as 2005 Para Que no me Olvides , 2002 El Alquimista Impaciente or The Impatient Alchemist and 2000 Sé Quién Eres .
