According to Taíno legend, the jupía are spirits who live on our earthly plane and who can adopt any form, usually female. They only go out at night to feed on guava and visit those places they once used to call home. But be careful how you invoke them. Police detective Tomás will learn how as he investigates his wife’s murder and daughter’s disappearance. All roads lead to a dilapidated nursing home on the outskirts of the city, where he’ll be confronted by Atabey, an enigmatic nurse with mysterious powers.
