Alice, a young girl, goes on holidays but her ship, Bubble, sinks. A dolphin saves Alice and helps her survive in the magic and unknown world of the sea bottom. She confronts Octopus-leg, the General of the sea bottom, the Jellyfish and other fish that imprison her, because they know people are hostile towards nature. Aiming to gain their favor, she becomes their teacher and teaches them how people think, talk and behave. She also talks to them about one of the most important things in the world: love. When a black spill threatens life in the sea bottom, Alice with the help of Immediate Action Wave comes up against it and saves her new friends. They, in exchange, give her what she mostly wishes: her return home.
