Nanna is sunbathing nude between her parents (who are also nude). She gets up and puts the suit on, meets with Niels and then kisses him for a present he gives her (and for saying she's cute).
The kids go swimming and afterwards Nanna takes off her swimsuit and lies down to dry off naked in the sun. Niels hesitates but soon does the same, and they look each other over carefully. Includes slow close up shots of their naked bodies.
A family discover that they are on a nudist beach. Mother, father and son have nothing to do but join this nude society. Rear nudity of character Jan Dvorák (called 'Honza', played by actor Marián Miks, 11).
