alright, so last summer I was watching tv in Poland and this movie came up late night, but I don’t remember what channel it was on. 

It caught my attention because t was a horror movie that had some very attractive scenes.

i don’t really remember the actors but it did look like a older movie, 80 90 maybe early 2000s.

The plot was about a couple who ran a undergound experiment it looked like and eventually, the main character, a male and detective looking, took a woman down there and tested the experiment on her.

she can was able to be both a human and this alien specimen looking thing and she eventually escaped leading our main character on a hunt to find her.

Pretty much the rest of the movie was the chase and she would have sex with all these guys and she had a tail that would pretty much kill the guys after the sex was over. The last scene the girl was having sex on a motorcycle I believe in like a garage, the movie was pretty dark throughout, as in the shading.

I don’t really remember most of the other aspects of the movie but would love to listen to anyone that would help.
