Alaska: The Last Frontier

After a long winter, cabin fever is setting in. Eivin and Atz get caught overnight in the backcountry and Otto gets an orphan calf to connect with an unwilling mother.

Before the spring thaw floods the area, Atz Sr. and his sons build a bridge across a river. Meanwhile, Atz Lee and Jane build a new smokehouse.

Atz and family head out on a black bear hunt. But as Jane's confidence gets stronger, Atz Sr's waivers. Meanwhile, Otto gives CPR to two prematurely born calves.

Atz Lee and Jane climb reefs to hunt for octopus. Jane must face her fear of heights or be trapped by the tide. Plus, Otto struggles to keep a newborn calf alive.

Eivin and Eve decide to finally add running water to their home. While Otto builds Charlotte a milking parlour, Atz and Atz Lee head out to hunt bear.

The Kilchers try to make the most of the long hours of sunlight. While Otto helps a cow with an udder problem, Atz Lee goes salmon fishing.

Atz Senior, Atz Lee and Jane travel to the highest peaks to hunt for wild goat. A wasp infestation destroys Eivin and Eve's bee hive and summer honey harvest.

The Kilchers come together to enjoy the fruits of their year-long labour. From Yule's famous nettlebread to Homesteader pie, nothing comes easy when making this feast.

A porcupine nails several of the Kilchers' animals with quills and removing them is a dangerous procedure. Atz and his family move an old abandoned cabin.

Atz and Atz Lee swim their horses across a chilly lake to get to bull moose hunting grounds. But the trip is made more difficult by uncooperative weather.

Otto decides to give his "Wacky Yak" to a friend, but the gift rejects the idea of being given. Meanwhile, Atz Lee gathers lumps of coal for his gifts.

Bears and wolves remind the Kilchers that humans aren't always the apex predator on the homestead, but threats to their welfare come in all shapes and sizes.

With winter on their doorstep, the Kilchers race to finish their summer projects. Plus, Otto's enormous new project strains his marital bliss.

Otto and Eivin use a duck hunt for some last minute father-son time before Eivin becomes a dad himself. Unfortunately, Atz and Atz Lee's bonding time is less fun.

Atz Lee and Eivin brave bears on a remote island to hunt deer. Meanwhile on the homestead, Charlotte and Otto try to save the life of their cow and her calf.

Fall is over and Eiven and Eve prepare for a new arrival before the freeze, and Jane faces wicked weather and quicksand on her first cattle drive with Otto.

The Kilchers' lifestyle is dictated by the seasons, from rescuing calves born in late winter snow to fighting swarms of mosquitos in almost 24 hour solstice sun.
