When troopers respond to a call regarding a discharged gun in the Mat-Su Valley, they discover a large stash of weapons hidden inside a boat. There is a good chance that the suspect is still armed and dangerous as officers venture out into the dark woods to search for him. Later, troopers patrol villages near Juneau, handle the fall moose hunt in the Denali wilderness, and search the southeast Alaskan ocean floor for a stolen firearm.

Troopers face a new set of challenges with an unforgiving blizzard setting in. Typical DUI cases are worrisome enough, but with roads frozen, it's a recipe for disaster. Even criminals scramble to get out of the cold as they turn themselves in on outstanding warrants just for a warm place to sleep for the night.
