CUCKOO Blu-Ray

Pining for her mother in a throng of bass-strumming and queer angst, teenager Gretchen wishes her mute stepsister Alma would just get lost. But when her estranged dad and his new wife accept creepy Mr König’s job offer to overhaul the architecture of a suspiciously Overlook-like hotel in the Bavarian Alps, Gretchen quickly regrets her sniping. There’s something stalking the woods in a pale mackintosh, hotel guests can’t keep their dinner down and a perverse experiment is proceeding unchecked – with dire consequences.
