David and his pet mouse, Jack, were visiting Granny and Grandpa when heavy rains flooded the farm. As the water subsides Grace, the cow, is left stuck in a tall tree. Would the animals rescue her? And how would they do it?
After initial opposition to helping Grace they realize that it is natural to look after one another. David and Jack lead the animals in the construction of the biggest, fastest and most beautiful slide in the whole world. Everyone has a part to play from the ducklings to Polly pig. Their amazing creation is not revealed until the very end. Grace is full of gratitude as she lands in the wool lined giant nest at the bottom of the slide. Even Richie, the selfish rat, learns that everyone has something to give when he plays a pivotal role in setting Grace free.
