Suburb

Suburb is a 1951 Argentine drama film of the classical era of Argentine cinema, directed by León Klimovsky and starring Pedro López Lagar, Fanny Navarro and Zoe Ducós. The film portrays life in one of the poorer neighborhoods of Buenos Aires. Under pressure from the Peronist authorities, Klimovsky changed the ending to suggest that the problems of such communities were now a thing of the past.
