Our world is so connected now that moments of solitude, peace and quiet can often be hard to come by without interruptions and distractions. From the real people in our lives to the virtual ones we interact with on Facebook and Twitter, there’s almost always someone else intruding on our private, little bubble. You’d think we could simply turn off the phone, iPad and laptop and go sit outside with a good book, but for many people that appears to be physically impossible. But what if you had no choice? An unnamed woman (Martina Gedeck) who we’ll call Frau (if only because IMDB lists her that way) arrives at a remote Austrian hunting cabin with two friends and their dog. They’ve only barely settled in when the couple decide to walk into town with the promise of returning by nightfall, but still absent the following morning Frau goes looking for them. She doesn’t get far as she collides with an invisible barrier blocking the road. She discovers that the “wall” surrounds an area several square miles in size with the cabin in the center. And she’s all alone.
