Get to know Winston, a tiny abandoned cub who imprints on Judy as she nurses him 24-7. Feel the heartbreak as she severs their emotional attachment and teaches this sweet little fellow how to be a grown-up, independent bear in the non-human world.

Welcome sisters Xiba, Xyla, and Xola, a trio of starving orphans who turn Winston's world upside down before gentle Xola teaches him a lesson about friendship. Then monitor new cubs Yasmine and Yara, who get reacquainted after a stressful separation.

Bone up on outdoor skills as Winston and the X girls move into their new fresh-air enclosure; witness Yasmine and Yara's kindergarten power struggle.

Experience the joys of rain and climbing with Yasmine and Yara, and watch Winston take a dip in his new pool. Go hunting for dropped radio collars with Roger and Steve, then see what happens when the two groups of summer cubs come face-to-face.

Spy on the summer cubs as they learn to climb trees and forage for food in preparation for their release into the wild; get surprised by a set of new arrivals, observe the annual pre-hibernation eating binge and enjoy a bear-friendly Thanksgiving.

Prepare for the summer cubs' release with Roger; meet Ace and Little Blueberry, two newbies with serious health issues who will have to stay over the winter with the Z cubs; six happy, healthy bears embark on their new lives in the wild.
