Criminal psychologist Kate Fuller is assigned to the murder of a man who has seemingly been strangled in his sleep by his wife and the only witness is their eight-year-old daughter, Sophie. As Kate digs into the mystery of an ancient demon which kills people in their sleep, she experiences the same petrifying symptoms as all previous victims and spirals through a chilling nightmare to save herself and Sophie before she dares fall asleep again.

Trivia, insights & behind the scenes
Javier Botet has Marfan syndrome, which gives his body its naturally elongated proportions—he's played monsters in Slender Man, The Conjuring 2, and Crimson Peak.
The film draws from genuine sleep paralysis folklore across cultures—Mara resembles the 'shadow people' and 'old hag' figures reported worldwide, making the horror weirdly anthropological.
