Ledoyen and Considine play a young married couple at the end of the 1970s, who come to visit a friend (Oldman) who now lives in the Basque region because he has married a woman from there (Sánchez-Gijón). Their tranquil summer turns to horror when they discover a girl with horribly mutilated hands in the forest. They try to help her by taking her away from the home in which she is locked, but the local villagers, who have to protect the girl, start a pursuit in the forest they know much better than the visitors.
