In a snowstorm on the grassland, a little girl wrapped in a wolf-skin cloak suddenly bursts into a pasture. Not only does she save two hundred sheep about to rush toward a cliff, but she can also understand messages conveyed by animals. Batu, a herdsman, takes in the child who calls herself Ana, only to discover that the red copper bell on her body is actually linked to a buried past of three years ago. As grassland crises emerge one after another, Ana uses a special way to help animals and herdsmen resolve difficulties, and also lets the truth hidden for many years gradually surface. When everyone thinks she is just a clue to the missing girl, they discover—she is the one and only Ana.
