It was the beginning of a new stage in his life, set in a neighborhood also made of many distinct levels. What does remain today from the famous 'Bairro Alto'? The prostitutes and journalists, the artists and artisans... What has been changing, and how does it affect the future of the city? We follow the faces and the voices that fill up the empty streets with excitement, both day and night, in an attempt to inscribe the memories and expectations, dreams and desires that make up the whole of 'Bairro Alto', in the year of its 500th anniversary.
