Inspired by the legend of La Llorona (the Weeping Woman), the story introduces a teen girl, Paola Santiago, who has always relied on hard science and logic to make sense of the world, unlike her mother, who believes in magic. But folklore becomes fact when Paola's best friend goes missing, and to save her, Paola has to enter a world of mind-bending monsters and relentless spirits steeped in Latin folklore that defy both logic and legend.
