Capivara, an oil rig worker, is evacuated to Rio de Janeiro after an oil spill contaminates the Brazilian coast. Despite the danger, Capivara just wants to return to the extraction fields on the high seas. In the city, he is helped by Ywy, a woman who convinces him to travel to her homeland of Mato Grosso do Sul, in search of a job in the monoculture plantations of soya and maize. She tells him about the infertility of those genetically manipulated seeds and of an android like her. Capivara, a human, is unable to understand.
