The prologue tells us of a father fleeing scandal, grabbing his children and speeding into the mountains. They crash, wind up at a remote cabin, and then something happens to him. Five years later, searchers find the girls, now feral, nonverbal, like rats almost. Their uncle (Nikolaj Coster-Waldau) takes them in, but his girlfriend (Jessica Chastain) is reluctant. Naturally, all is not as it seems, thanks to whatever kept them alive in the woods. Chastain and the girls, Megan Charpentier and Isabelle Nélisse, are great. A solid ghost story.
