Do you know how the New Year begins? It is kept in Santa Claus's bag among the gifts for the children. At the twelfth stroke of the clock, Santa Claus opens the bag, and the New Year comes into its own. But one day, on the very eve of the holiday, Baba Yaga steals the New Year's bag, and the threat of remaining in the past hangs over the world forever. The situation is complicated by the fact that Santa Claus himself does not remember anything about what happened. His old friends, the guys from the House of Culture, come to help grandfather.
