Routine calls can often turn life-threatening in an instant, which is why Alaska State Troopers know to always have their guard up. Embed with officers as they handle a felony stop on the icy streets of Fairbanks, save an innocent pooch from the wrath of Alaskan wildlife, and patrol the dangerously thin icy waters of the Mat-Su Valley's most popular ice-fishing lakes. Up north, Troopers are on the hunt for a dangerous wild lynx that is wreaking havoc on the community's pets — and it might turn on the neighborhood kids next.

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.
