In an unnamed Latin American country, a mysterious plague quickly spreads, erasing the memory of anyone infected. Angustias Romero flees with her family, but their flight is tragically cut short when she loses both her children. Consumed by grief, she finds herself within the hallucinatory expanse of Mezquite – a town corrupted by greed and populated by storytellers, refugees, and violent, predatory gangs. Here, Angustias is finally able to lay her children to rest at the Third Country, a cemetery run by the larger-than-life Visitación Salazar and a refuge beyond suffering and fear. While Visitación remains defiant in her mission to care for the dead, the cemetery she oversees is the focal point of a bitter land dispute with Alcides Abundio, the most feared landowner of the border.
