Windy Lake First Nation is hosting the annual Trappers Festival, and the four Mighty Muskrats are excited about the sled-dog races and the chance to visit with family and friends from far and wide. But during the Teen Sled Race, the lead dog is the victim of a frightening accident that may be more than it seems.
