One day Chicken Little(Zach Braff) tried to warn everybody the sky was falling,that his world began falling apart. The worst blow of all, chicken little's father dont believe him. In fact, his father was just plain embarrassed by him. But, today is a new day, Chicken Little has a plan to erase that defining moment from the minds of the townspeople, or townsanimals, and to make his dad proud of him.

With the support of a few good friends - Abby "The Ugly Duckling" Mallard (Joan Cusack), a pig named Runt of the Litter (Steve Zahn), and "Fish Out of Water" (Dan Molina) – Chicken Little gears up and joins the baseball team. Of course, he hits the homerun that saves the big game, and thereby carries on his dad’s hometown hero baseball legacy.

Unfortunately, just when things start to go his way, it happens again. That pesky octagon shaped piece falls right out of the sky. Luckily, his friends are there beside him when he happens upon the cause of the falling sky and tries to warn everyone, again. By the time the town, and Chicken Little’s father, figure out he’s telling the truth, it may be too late.
