In mid-December, the cat with a sack will see its premiere, which helps in determining what is the essence and what is not necessary to accumulate.
Among the beautiful luxurious houses there is also one a little less luxurious, in which a boy and a girl live with their mother. One day, the children will want everything that the neighbor's children have. A cat appears in front of them, holding a sack containing a miraculous machine. He can create a thousand things from one thing, and nothing is impossible. But slowly, in this abundance, the boy and the girl realize that they were happier before. The hanging cat is thus an assistant in the search for essentials.
