After an unfortunate bookcase collapse, Alien suddenly finds himself jolted out of his story and into a very strange world, complete with talking bears. Desperate to return to his book, Alien asks the Bear family for help so he can get back to his story and save his beloved Planet Zero from total destruction before it's too late.

Mama Bear and Papa Bear try all kinds of zany contraptions (with some help from their nemesis, Goldilocks) without much luck. Baby Bear might have the perfect solution to get the Alien out of the woods and back to his planet...but will anyone listen to the littlest voice in the story?
