The Last Alaskans

It's Fall In the Arctic National Wildlife Refuge, and that means animals are on the move. Heimo pursues the tail end of the caribou migration, a bear ransacks Bob's cabin, destroying 2 years of dry meat, and the Lewis family arrives to sign of moose.

Winter is coming, so Heimo pursues a moose that will feed Edna and him for months. Meanwhile, Bob packs up his hunting gear, but runs into trouble when his boat's engine malfunctions; and Tyler and Ashley find their cabin flooded by a rising river, and later, after a week of salmon fishing, their catch is raided by a bear.

A hunt for a bull moose, which can feed a family for the winter, is critical before temperatures drop to 50 degrees below zero and can make being outdoors even more dangerous.

Heimo begins trapping, but must find a way across a newly frozen river; Bob deals with the fallout of his plane crash; Ray and his daughters try to increase their food supply.

Bob visits his daughter, and assesses the damage of his crashed plane; Tyler and Ashley travel 15 miles to a lake cabin to run their dog team and look for food.

The first day of darkness arrives, but Heimo's in jeopardy of being caught miles from home. Meanwhile, the Lewis daughters get ready to leave the refuge to live on their own in town.
