Undine is a historian. She works as a guide and lives at Alexanderplatz in Berlin. Behind the facade of a modern life, however, lurks an old myth: If the man she loves betrays her, she must take his life and return to the water. So when his boyfriend Johannes leaves Undine for another, he puts his own life in danger. But later that day, Undine meets the diver Christoph. An encounter that strikes such powerful sparks that a large aquarium explodes over them. Can Undine escape the myth?
