All the girls of the Kholmogory principality dream of a wedding, and only Vasilika does not want to get married at all. It’s better to become a free bird - a student of the witch Yagini in the witchcraft Forest, cast a spell on blood and love whoever you want. But witches, it turns out, work from morning to night, and mortal dangers await in the Forest - if the mermaids don’t fool you, if the Navi spirits don’t lure , so the dashing black-haired horseman of the Night will lure... Vasilika will have to flee to the kingdom of Death to Koshchei the Immortal himself. Will she endure severe punishment for her frivolity? Will he make new mistakes?
