Jorge Preloran filmed a genre of his own, ethno-biographies, for more than twenty years. By focusing on one character and following him or her for a period of time, Preloran achieved profound portraits that express the particular vision of the world of different people. 'Traces' is an ethno-biography, but in this case the character is Preloran himself, and the director a disciple of his. The movie unravels the life of Jorge Preloran, the way he did with his own characters. From a childhood signed by asthma problems, a high class family and a strict education to becoming a man who changed the cinema, creating a new genre.
