Squirrel lives in the woods for a year. She experiences the seasons for the first time, including winter. She explores the setting, finding shelter in trees, drinking and bathing in streams, and finds many other animals (including chipmunks, which she can hunt). Squirrel survives by hunting and walking to nearby houses to eat from garbage cans.

While wandering for food one day, Squirrel sees Bone across the highway. She rushes toward him but realizes that it’s a different tan dog, who is smaller than Bone. The dog’s name is Moon. They become friends right away. Moon is playful and loyal. They go to the woods together.

Squirrel and Moon ransack the garbage of nearby houses. Moon is brave and bold like Bone, so she rushes to the garbage. The humans start tying down their garbage lids.

Soon after, Moon leaves their nest in the woods. Squirrel is more independent but wants to stay with Moon, so she follows along. They wander the land while the wintry weather comes and finally find a barn to sleep in.
