I saw this movie on tv, about 20 years ago. It was in color.
Plot: It was set in a futuristic dystopian world, where people can connect to the internet through ports in their head (similar to The Matrix). There was some kind of serial killer killing people on the internet, and they would die in real life. There was a man and a woman who were sent to track down this killer, and eventually found him hiding inside a large mega-corporation. The ‘Final Battle’ consisted of the woman jacking in to the internet, and fighting this killer online, going through mazes and such to get to the man. I cannot remember anything else.
