Far away in the North in a small poor yaranga lived a widow with her son Yatto and daughter Tayune. The children were lazy and disobedient, they did not want to help the mother and collect firewood for the fire (Tayune was more concerned with her long beautiful braids). And when the fire in the hearth was extinguished, the evil old woman Purga burst into the yaranga. Mother tried to protect her children, but Purga carried her away. Brother and sister had to forget about their laziness and go in search. They went a long way and overcame many dangers before they could find the home of Purga and save their mother.
