Clara is no ordinary cow—she dreams of going to space! While the rest of the barnyard laughs at her wild idea, Clara refuses to give up. With the help of her best friend Gizmo the goat, she trains in hilarious ways, builds a rocket out of farmyard scraps, and blasts off into the stars. Along the way, she tumbles through zero gravity, befriends curious aliens, and proves that even the most unlikely dreamers can reach the moon. After a bumpy return home, Clara becomes the barnyard's first "Moo-naut" and inspires her friends to chase their own impossible dreams.
