Hello Everyone I saw this movie and cannot remember the name. It goes like this, there is a man and a lady who eventually perform an experiment on the lady and she turns into like an alien but she is also human. She has targets and has sex with them and once she is done she turns into an alien and kills them. The main character a guy is trying to rid her of this alien quality. This is a pretty broad plot I just stated but I watched it awhile ago. I believe the woman was blonde.
