Moody teen Gretchen (Hunter Schafer) was less than thrilled about having to pack up indefinitely for a Bavarian Alpine resort as her architect dad (Martin Csokas) and stepmom (Jessica Henwick) worked on a project for the chalet's eccentric owner (Dan Stevens). She'll soon discover that there were justifiable--and unholy--reasons to find her new environs and host off-putting. Chiller from Tilman Singer ("Luz") co-stars Mila Lieu, Greta Fernández, Astrid Bergès-Frisbey. 102 min. Widescreen; Soundtrack: English.
