T.J. Särkkä – Kuu on vaarallinen AKA Prelude to Ecstasy [Uncensored] (1961) 

IMDB wrote:
An atmospheric indian summer triangle drama.
Decent melodrama from the studio era. Liana Kaarina plays a vamp-like young vagrant hitch hiker, who gets a ride from older industrialist who consequently takes her to his summer house to be his mistress. She takes full advantage of the situation and plans a prosperous marriage when she meets a young man while skinny dipping…

Surprisingly fresh effort from (the biggest studio mogul of Finland) Särkkä, who (with great help from the master cinematographer Olavi Tuomi) succeeds in creating a suitably sleazy atmosphere to unfold the drama in.

This one was a big success at first release and was sold to 32 countries. Mostly because of the nude swimming, I presume…
