As the Alaskan summer heats up, so does the crime. In the remote area surrounding Glennallen, Troopers search for a family of missing moose hunters. Because the terrain is expansive and difficult to cross on foot, Trooper Dahl takes to the skies in his floatplane. It's not long before he spots the stranded family's vehicle trapped in a creek below. In Seward, the Fourth of July is creating an excuse for reckless behavior.

Summers in Alaska bring out some of the state's wildest creatures, and some are surprisingly human. In Wasilla, a crazed man is caught bashing in an unsuspecting woman's windshield with his bare hands. In the remote village of Kongiganak, Trooper Hightower flies over to respond to an arson arrest. The mission takes a turn for the worse when they are called to an ensuing fight with knives and Tasers. In Fairbanks, Trooper Mealey receives a report of teenagers illegally hunting migratory birds.
