Being brave when you feel afraid is the very bravest brave of all. It's time for Arlo's family to leave their winter den and journey to Spring Valley, but he isn't so sure about all this change. Arlo likes their home just as it is; and after all, his sister, Eva, is the brave one. But when a snowstorm separates them as they travel through the Great Wood, Arlo finds that when it's his turn to be brave, being afraid won't stop him from saving the day.
