An oil spill contaminates the Brazilian coast. Capivara, an offshore oil rig worker, is evacuated back to Rio de Janeiro, where the locals remain ignorant of the incoming disaster. Despite the danger, Capivara wishes only to return to the offshore oil fields. In the city, he is aided by Ywy, a woman who convinces him to travel to her homeland of Mato Grosso do Sul, in search for work in the soya and corn monocultural plantations. There, Ywy tells him about the infertility proper to those transgenic plants and an android like her. But Capivara, a human, is incapable of understanding her.
