In a desertic future, Suzana, a young agricultural machine operator, lives and works on the industrial corn farm inherited by Douglas Júnior, in the countryside of Santa Catarina. She divides her time between long working hours and the house where she lives with her mother Nera and her sister Lulu, who has a respiratory disease. In a region without hospitals, the virtual doctor informs them that only an expensive medicine can treat the child's illness. When Suzana receives a proposal from her new boss, a mission to increase the farm's profits, she accepts, despite the risk, because she needs to help her sister.

Heading towards the border with Argentina, she ends up giving a ride to Milagros, a Uruguayan street artist with a punk look, who is secretly a hacker. On the way back, the police intercept the truck and they flee, abandoning the vehicle and its cargo. From the news, they discover that they were transporting pesticides, cocaine, and electronic cigarettes. In search for food, they trespass on an agroecological refuge run by two armed elderly women, who force them to work on the land.

Over time, Suzana and Milagros gain the women's trust, who reveal links to activists, and the relationship turns into friendship. Helped by the elderly women, the two head to the capital: they hitch a ride on a coal train and are welcomed by a group of Milagros' hacker friends. The collective invites Suzana to participate in a cyberattack on a large chemical industry, promising her the money she needs to save her sister. Suzana accepts, but after calling her sister and being answered by Douglas, she decides to leave, taking money, a gun, and a car that belonged to Milagros's group.

Upon returning, she finds her mother alone: Lulu died from lack of help. Enraged, Suzana breaks into Douglas's room, where he is sleeping. She points a gun at his head and drowns him with pesticide. She sets fire to the house where she lived, and in the end, mother and daughter leave the burning farm behind.
