Excuse my bad english... I'll try to describe movie that I've barely recall. Movie is uncommon. I presume that is made in some Scandinavian countru, back in '80's (or early 90's, maybe late '70's).

Theme of the movie is centered on guy, who goes around with a hand-camera and records everything, randomly. It's like he's want to made documentary film or something like that. Suddenly, he step into the room where his female cousin making love with her boyfriend.

Thanks.
