Two children wake up to hear the lake singing, then the wind begins wailing...or is it a wolf? They bundle up and venture out into the cold, carrying their skates. On the snow-covered shore, they spot tracks made by fox, deer, hare, mink, otter...and the wolf In the bay, the ice is thick and smooth. They lace up their skates, step onto the ice, stroking and gliding, and the great lake sings again.
