Set in a frozen Arctic landscape where aurora lights shine across the beautiful night sky, the segment introduces three humpback whales. Two of them are adults, and the third is their little baby who appears to be feisty and loves to swim around and jump high out of the water.
The baby humpback follows its parents to the surface where they jump and splash in and out of the Arctic waters until they rise out and fly except the baby humpback. After a few jumps, it finally manages to get airborne and joins its parents. It suddenly spots a group of seagulls and decides to fly with them but instead makes them annoyed. The angry seagulls chase after until the baby humpback escapes into the water and becomes trapped inside a huge iceberg.
Surrounded by frozen icy walls, the baby humpback appears unhurt but all alone in the dark icy caverns. It begins to explore the cave searching for a way out. Beneath the cave's waters are many spiky icicles in every direction. It rises to the surface and sees its mother's shadow whose on the other side of the ice walls. The baby humpback desperately tries to get to it and follows its parents' shadows to a light. Once it swims inside it, it begins to float to where the light is shining from and is reunited with its parents.
As the brightest star flashes, the three whales return to the waters and join a larger pod of humpback whales. Soon millions of humpbacks take to the sky and fly across a forest landscape to the top of the clouds. They fly towards a storm cloud where bright light is shining from it until finally, they rise out of the waters where the star shines like a nighttime sunrise.
The scene where millions of humpback whales take to the sky and fly across a forest landscape to the top of the clouds, represented Fantasia 2000 in the finale segment of Wonderful World of Animation.
