When Belinda Buttercup becomes trapped in a water lily on the Blossom Land Stream, the swift-moving current carries her away. Belinda's family and friends hurry to save the tiny Blossom child before she reaches the Loud Waters, where crashing waves destroy anything in their path. Even more dangerous are the Big People, who are destroying the Blossom Land Forest and building huge dens to live in. The little people of Blossom Land and their forest friends vow to do whatever it takes to stop the Big People from destroying their beloved home─but first, they must save Belinda.
