The resort is run by the creepy Herr König (Dan Stevens), who offers her a job at the reception which she jumps at thinking she can get some money together and run away.
Some of the resort guests behave oddly and she has a frightening experience with a woman who seems to chase her in the dark, so when a glamorous stranger offers her a ride to Paris she grabs money from the till and leaves.
No good will come of this.
This sort-of body horror from Tilman Singer is plain weird but all the better for it. Gretchen wants nothing more than to be gone but strange things are afoot and she finds herself wanting to protect her not quite family.
Hard to say much without spoilers it's just weird in an X files episode kind of way and not scary or very violent. 7/10 worth a look.
