Die Wand (2012)

The protagonist of the film is an unnamed woman (played by Martine Godette in other people's lives). She went on holiday at the foot of the Alps with two friends and their dog. After settling down, her friend suggested going out for a walk, but she decided to go to bed early because she was tired of driving. When she woke up the next morning, she found that her friends had not returned all night, and only the puppy Lucius was by her side. Worried, she thought of the nearby village for information, only to find that she was sealed off by an invisible barrier and could not leave at all. When the radio station was cut off and the phone lost its signal, she had to decide whether to risk death and climb over the mountains behind to find contact with the outside world, or to stay here to avoid the danger of being invisible.
