An elderly hermit crab unleashes a cascade of paradoxical but reliable stories on his fellow tribesmen, based on the adventures of a mysterious creature named Milyul. Wild circumstances force her to think about the questions: “Who am I? Where? What kind of world is this? Am I a man, or a frog princess in the corrupted kingdom of Koshchei? The world is much more diverse than naive assumptions. Over the course of a week of awakenings on different ships, surrounded by people different from before, Milyul rushes through several generations of a family, the head of which begins to consider her an inevitable family curse. How will the knot of cause-and-effect relationships be unraveled? Will there be any sympathy for the violent monster that has emerged from the 6-year-old girl Milyul? Is it possible to explain the inexplicable, and how will the dangerous experiment of an old hermit crab on the shores of the Indian Ocean end?
