A girl has a man come in to her life and she doesn't trust him and tries to find out who he really is. The girl has aboyfriend and there are some sex scenes in this movie. The man is a murderer and tries to kill the kill at the end I even think he watches the girl have sex while in the house. I watched it in the late 80's so I think it is an 80's film. Not much to go on but I know it wasn't a high budget film and defo american. I know the girl goes to another town to try and find the mans past. He may even be her mums boyfriend. Hope that hepls.
