The government of a country (possibly in Africa) decide to build a dam to provide electricity. The local population are carefully moved out of the area, but some animals are left behind. realising their peril, they decide to build a raft in order to escape the rising waters. They face various problems, including sabotage by Hyena, but eventually they sail away in their ark and arrive safely on dry land. A separate chorus and instrumental group provide the music, while a cast acts out the story.
