Nyuma, the thirsty fish tells the story of a little blue fish like no other. He is curious and has an exceptional gift: he can breathe on land and speak the language of humans. Despite the water all around him, Nyuma feels a strange thirst, much greater than a simple need for drink. Accompanied by Ngerria, a wise man who breathes underwater, and Nguvu, a courageous young man, Nyuma explores the rivers, the land and even the galaxy to understand the secrets of water and restore the balance of nature. 
Through his adventures, he discovers that his thirst is also a quest for knowledge, Justice and hope.
