This season, The Last Alaskans face obstacles brought on by the unforgiving environment, including rising predator competition and the aftermath of forest fires, as well as the deeply personal challenges. After 40 years in the Alaskan Wilderness, due to the return of his cancer, Bob Harte must move away from the refuge and into town with his daughter and granddaughter. We will follow Bob's hard-fought battle to the end and get the chance to say goodbye. For Heimo and Edna Korth, this season brings an opportunity they have dreamt of for years: their daughter Krin and her family will attempt to survive a winter in the refuge. There's also another new face this season, as Tyler and Ashley Selden bring their baby girl Sidney into the refuge. They look to improve their property and face the challenge of balancing the demands of being parents, as well as providers for their newest member. Charlie Jagow faces one of his toughest challenges this season in the aftermath of the summer fires. He must re-establish 40 years' worth of family traplines. These families and trappers will be challenged like never before as they look to continue the unique life they've built in the refuge.
