This deeply human documentary examines the subject of environmental destruction, highlighting the impoverished migrant workers who are chopping down the Amazon rainforest to create charcoal for pig iron production used primarily in the automobile industry. The film examines the children and elders and their daily lives and work as they burn timber in igloo-looking huts, their bodies charred gray for $2 a day, struggling to survive.

Estamira is a 63-year-old woman who suffers from schizophrenia. She leads a tough life and has supported herself for the past 20 years by picking through garbage at the Jardim Gramacho Disposal Area in Rio de Janeiro. The film follows her starting in 2000, the year she begins treatment in a psychiatric clinic. At first, it is hard to understand her in her stream-of-consciousness sentences, delusions and obsessions. Gradually, however, we get to know her as a woman who can have quiet and lucid moments despite her illness.
