Meet the Kilcher family, who live on a 600-acre homestead in Alaska. With another brutal winter approaching, and bears having killed two of the family's cattle, they are forced to pin all of their hopes of surviving the winter on one last hunting trip.

The first storm of winter approaches as the family races to finish preparing for the next eight months; Atz herds cattle across flooded glacial rivers.

The storms hit earlier than expected; search for a newborn calf and its mother; Otto builds shelter for his herd.

Desperate for food, the Kilchers struggle to get through a harsh winter.

Spring arrives and the family deals with a rogue hen and hunts for food.

The family battles danger to drive their cattle to the summer pasture.

Atz begins range riding to protect Otto's cattle herd from predators.

The Kilchers call in favors to help build a fence before the high tide.

The Kilchers fish for the hundreds of pounds of fish needed over winter.

Fall arrives and the Kilchers scramble to finish their winter preparations.

Otto's sense of humor and ingenuity inspire his family and neighbors.

The Kilchers must not only reuse and recycle, but also reinvent.
