7 August 2013 Last updated at 17:01 BST

A slum dweller from one of the toughest neighbourhoods in Buenos Aires has made a film about the harsh realities of life in the city's slums.

Diagnosis Hope is a semi-autobiographical story following a former teenage inmate as he attempts to break out of a life of stark poverty.

Having spent three years in prison himself, the director - Cesar Gonzalez - says he is in a unique position to challenge negative stereotypes about people like him.
