Some people go to the mountains for vacation, for a little rest and relaxation, not for a sinister and terrifying experience, like the one you see in “Cuckoo.” This movie from German director, Tilman Singer, is about a teenager, Gretchen, who ends up moving with her Dad, her stepmom and much younger half-sister to a mountain resort in the German Alps. There, they are greeted by Herr Konig, who runs the resort and for who Gretchen’s Dad and stepmom will help build a new resort. Gretchen gets serious “stranger, danger” vibes immediately from Herr Konig, played by Dan Stevens, with his creepy voice and suspicious ways of touching her. Gretchen, played by Hunter Schafer, is a fish out of water here and she also soon sees some undoubtedly strange things around the resort. She’s already the stereotypical angst-filled teenager, but soon she also finds herself chased by horrifying entities, and trying to help a cop figure out who’s responsible for several murders at the resort. All while, trying not to get killed and survive one more minute with her stepmom and half-sister, whom she despises. It’s a mountain of trouble in the German Alps and Gretchen just isn’t having a great week. Is it worth your 90 minutes to see why? Check out this episode to find out. “Cuckoo” also stars Jan Bluthardt, Marton Csokas, Jessica Henwick, Mila Lieu, Greta Fernandez, Proschat Madani, Astrid Berges-Frisbey, Konrad Singer, Kalin Morrow and Johannes Benecke.
