In this very nice mini series, there is not much nudity.
There is however one scene at a nudist beach. This scene is at the 14th minute of the second episode, and also at the 48th minute of the 3rd episode.
Adam Pålsson and Simon J. Berger show most nudity.
We see Adam Pålsson's butt and also his big balls in between his legs, when he is swinging over the lake.
