In a small village on the banks of a cursed river, only the courage of a desperate girl will find the thread between life and death. Along the fast river, where houses are built on stilts, lives a girl named Luna. All her life she had heard tales of a time before the mound, when fairies danced in the streams and no one suffered from the mysterious fatal disease that made you choke on river water. However, these are just fairy tales; no reasonable person believes in them. However, in the depths of the waters, not everyone will agree with such ignorance. The river fairy Utopia bathes in cheerful splashes and sadly awaits the day when her people will complete a portal to another world unknown to people. But when Luna’s younger sister catches swamp fever and has only three weeks to live, Luna sets out to find a cure for her beloved sister and no matter what it takes. Even if you have to believe in magic.
