After a long winter, Alaskans greet the emerging spring full throttle and for the most competitive among them, spring means one thing: the world-famous Iditarod Sled Dog Race. The Alaska State Troopers are on hand to start the race off safely. Meanwhile, Troopers respond to a woman scorched by the out-of-control flames of a bonfire, but they have a hard time getting the full story out of her. Elsewhere they're on the hunt for a wanted and armed man through the frozen backcountry roads of Fairbanks, and Troopers also get a call from a well-known dogsledding family whose sleds have been burgled.
