This movie fails utterly as a porn movie. The porn scenes are boring and completely unexciting. The famous sisters Tukiainen are seen at the beginning, thankfully for just one or two minutes. They aren't exactly known for their acting skills. (Nor do they do any porn, which might have had some novelty value.)

However, if you ignore the porn, you get an entertaining speculative fiction movie. Two movies, in fact - first, the prehistorical fantasy about a tribe of men-enslaving amazon-like women living at the shores of lake Saimaa, and a modern social porn movie about an alcoholic man and his daughter living in poverty. Apparently the girl and her girlfriend are descendants of the prehistoric tribe and keep abusing men like their ancestors. Although the "abuse" in the second part is more like "let's have group sex with all the men we can find".

One of the amazons somehow still exists in the modern time but only appears once and doesn't really do anything.
