Reluctantly, 17-year-old Gretchen, played by Hunter Schafer, leaves her American home to live with her father, played by Marton Csokas, who has just moved into a resort in the German Alps with his new family.

When they arrive at their future residence, Mr. König, played by Dan Stevens, Gretchen’s father’s boss, greets them and takes an inexplicable interest in Gretchen’s mute half-sister Alma.

Something doesn’t seem right in this tranquil vacation paradise. Strange noises and bloody visions plague Gretchen until she discovers a shocking secret concerning her family.

German director Tilman Singer shot on 35 mm, creating a gritty, edgy film.
