The action takes place in a post-apocalyptic world. A lonely man is trudging through sand under the scorching sun. This is Mikhel, a scientist. He is not afraid of strange beasts, or the strange world around him; he got used to all of that long ago. Suddenly his path is blocked by an endless black wall that seems to have appeared out of nowhere. He notices a small opening in the wall and, peeking through, sees a beautiful park with a pond, surrounded by trees. But the most surprising thing is that in the middle of this oasis he sees his wife and daughter whom he had lost in the cataclysm. Mikhel tries various methods to get over the wall. But as soon as he manages to do it, the beautiful world that he was striving so hard to get to always appears on the other side.
