Journey to Alaska for a true-life adventure with a family of brown bears facing the challenges of one of the world's last great wildernesses.

Reilly (Wreck-It Ralph, Magnolia) -- captures a year in the lives of mother bear Sky, father bear Magnus and their two cubs, Scout and Amber. Over the course of the year, the bears face ongoing threats to their survival, including avalanches, food scarcity, rival bears, and a vicious pack of wolves that lurks in their shadows. But throughout their struggles, the bears share touching moments of tenderness and create for themselves a life of unparalleled beauty.
