In the final episode of her epic Alaskan adventure, Sue Perkins heads even further off the beaten track, visiting amazing communities living in the extreme wilderness. She meets inspiring Alaska Native communities, discovers the challenges of life on the edge, and asks what the future holds for this great state.

She begins her journey by facing up to her fear of flying – though before she even steps onto a plane, she has to survive a heart-racing air crash simulator. Then it's up and away as she takes off to see the breathtakingly mesmerising Kennicott Glacier, and parts of Alaska unreachable by road.

Next, Sue heads to the formerly abandoned ghost town of McCarthy where she encounters the enterprising Alaskan spirit which is restoring this off-beat sin-city settlement back to its former glory. From there she goes deeper into interior Alaska where she meets an Alaska Native family to learn about Indigenous life, culture, and cuisine.

Before she leaves the beaten track behind, Sue travels along the mighty Yukon River to the Native Village of Tanana, discovering the challenges faced by this age-old community. Finally, she rounds off her trip by exploring true wilderness in the mind-blowingly massive Wrangell St Elias National Park – an area that's the size of Switzerland.
