With winter on their doorstep., the Kilchers race to finish their summer projects. Otto's enormous new project strains his marital bliss. Atz's horse strands him on the range. Eivin works some chicken magic. Atz Lee teaches Jane to fell a tree.

Atz Lee and Eivin take a bushplane and brave bears on a remote island to hunt deer. Charlotte scrambles to save a cow that went down during birthing. A very pregnant Eve struggles with the chores while Eivin is away. Atz cleans his chimney Kilcher style.
