A dry spell has lowered the water level of Lake Wanasink Lake, which leaves one of George and Allie's fish friends trapped in a small pond away from its family! George digs a canal with a lock between the lake and the little pond, but he can't get his fish friend to use it. Can a monkey and girl find another way to get the fish back to its family?

ジョージは黄色い帽子のおじさんたちと一緒に湖に泳ぎに行くが日照り続きで湖の水位が低くなっていて泳げない。そのうえ湖畔に土手が出現して小さな池ができており、一匹だけはぐれた魚が迷い込んでいた。
