After a fierce winter storm separates Mama Bear and Little Cub from their family, they must navigate the icy and treacherous landscapes of the North Pole to reunite before Christmas. 
Guided by the North Star, the pair encounters helpful Arctic animals like terns, a seal, a snowy owl, and even Santa’s reindeer, who offer clues and advice. Along the way, they cross frozen rivers, climb snowy hills, and venture through glittering caves and magical ice forests.
