Hidden Wall

The protagonist of the film is an unnamed woman (played by Martina Gedet in "The Lives of Others"). She went on vacation to the foothills of the Alps with two friends and their dog. After settling down, her friend suggested going for a walk, but she decided to go to bed early because she was tired from driving. When she woke up the next morning, she found that her friends had not returned home all night, and only her dog Lucis stayed with her. Worried, she wanted to inquire about the news in the nearby village, but found that she was sealed here by an invisible barrier and could not leave at all. The radio station was interrupted and the phone lost signal. She had to make a decision: should she risk her life by climbing over the mountain behind her to find contact with the outside world, or should she stay here to avoid the danger that the outside world could not see?
