A middle-aged woman spends a few days at a friends' game lodge in the Alps. When the befriended couple has not returned home one night, she, accompanied by their dog Luchs, goes in search of them. In the mountains, she encounters an invisible, impenetrable wall that completely isolates her from the rest of the world. Gradually, it dawns on her that she may be the sole survivor of an unexplained disaster. Together with Luchs, a cat and a cow, she faces the fight for survival and becomes more and more part of the inhospitable nature around her. The Wall is the story of a forced rebirth and a compelling plea for care and compassion towards all life.
