There are still water spirits among us. One group lives in Prague, led by Mr. Wassermann, who is using his wife's family as a servants. All they need is their old house near the river. But the house is to be demolished. They have to stop it. And the only way is to drown Dr. Mrácek, who is responsible for the demolition. But he falls in love with Wassermann's niece Jana. He changes to fish, is mistaken for water spirit from Germany, is drowned and revived again. The other problem is the flour with ears... and so on...

The little mermaid rescues a prince from drowning and falls in love with him. To be with him, she makes a deal with the evil sorceress: her beautiful voice against a life on land. It seems to work at first, the prince is enchanted with her lovely appearance. But the memory of a foreign princess still haunts him: The one who found him on the beach where the mermaid had left him, and whom he (of course) believes to be his saviour. To resolve this mistake is too much for the mute little mermaid, and not even her father, king of all seas, can help her in the impending catastrophe.
