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.

Little kids, little worries, big kids, big worries, sighs many a parent often. This is no different for the mother of eighteen-year-old Frantisek, who has just graduated from high school without much glory and is about to start his first job. Fandy is still full of boyish dreams, yearns for a career as a rowing representative, competes with a friend for the favor of an admiring girl and is generally stubbornly opposed to taking life seriously.
