A young English couple (Paddy Considine and Virginie Ledoyen) are going through a rough patch and decide to spend some time in the Basque country with their old friend Gary Oldman and his wife. But their tranquil '70s summer holiday turns into a nightmare when they discover a mutilated girl chained up in the forest. They attempt to rescue her but the locals have their own ideas about her fate, and are not about to let a bunch of meddling tourists stand in their way. 'Funny Games' meets 'Deliverance' meets 'Straw Dogs'.
