From a desolate environment comes an exuberant story. Acquaria shows a distant future in which the "Blue Planet" can no longer be called such. The Earth is practically exhausted after constant aggression against nature. All that is left are ruined cities and a few groups of people surviving in a devastating scenario. After years of exploitation and aggression against nature, water on planet Earth has come to an end.

In this arid environment, Sarah and Kim live the saga and adventure of surviving in Acquaria, a place full of dangers and mysteries. With their friends Gaspar and Guili, they live challenges and emotions in search of the rarest and most precious commodity on Earth: water.
