In a tiny, isolated, and highly superstitious Argentine hamlet, Lucho (Luis Ziembrowski), a simple woodcutter with an intellectual disability, lives with his elderly mother Ercilia (Marilú Marini) and his mentally disabled sister Roberta (Paula Brasca). Roberta serves as the town's prostitute, but Ercilia manages her work under strict rules to protect her. When El Loro (Germán de Silva) brutally breaks these rules and murders Roberta, Ercilia places a dying curse on the village. Devastated by the loss of his sister, Lucho loses his grip on reality and embarks on a violent, bloody rampage to wipe out the corrupt villagers.
