Cuckoo

After the death of her mother, grieving teenager Gretchen moves with her father Luis, stepmother Beth, and mute half-sister Alma to a resort town in the Bavarian Alps. The family is there to help build a new hotel, overseen by the enigmatic Herr König, who offers Gretchen a job at the front desk to help her adjust. Soon after their arrival, strange things begin to happen. While working at the reception desk Gretchen encounters multiple female guests vomiting, Alma suffers seizures triggered by a mysterious reverberating shriek, and Gretchen has a terrifying encounter with a hooded woman while biking home one night, but the incident is dismissed by police as a prank.
