George is having the time of his life playing with his toy boat in a large pond. After one day of playing, though he comes back the next to see his pond almost empty. George finds out that the water is being held back by a dam that was built by a family of beavers, and they will not let him play in their pond. So George gets the idea to build a dam of his own to make a new pond. He later finds out that water is just as important a part of a beaver's home as the dam.

Coco möchte mit einem kleinen Segelboot im Bach spielen. Aber da sind Biber, die den kleinen Affen nicht in ihrem kleinen Stausee dulden. Darum beschließt Coco, sich selbst einen See mit einem Damm zu stauen. Genauso, wie die Biber es getan haben. Doch das ist gar nicht so einfach.

George fa amicizia con una famiglia di castori e si entusiasma per la loro diga...

田舎で過ごすジョージの楽しみは池でのボート遊び。ところがある日池に行くと、水がほとんどなくなっている。上流に行ってみると、ビーバーがダムを作って川の流れをせき止めていた!
