As the winter twilight settles in, Alaska's State Troopers know that not everything is always as it seems. Troopers set up decoys to catch unsuspecting illegal hunters, try to solve the mystery of a disappearing dead moose, uncover clues that lead them to a well-organized crime ring, and help investigate a bloody potential homicide scene. A fiery gas station explosion lights up the night sky, and Trooper Cronin can't seem to catch a break during his hectic shift. Troopers Altepeter and Young encounter dangerously wintery commutes in their respective patrols, both on land and in the air.
