I need to find this movie so please help me. The only thing I remember about this movie is the ending so the details I can offer are very limited. I'm guessing that it's set in 1980's America for no other reason other than it appeared to be a big budget movie. The male character is naked and seems to be in the midst of some sort of apocalyptic melt down. There's a woman who seems to be the antagonist and I think she's killed everyone else because I can't remember any other characters. The man pretends that he's into her but when they begin kissing he impales her in the back with a sword piercing and killing himself in the process. The only other thing that I can recall is that there's loads of bright flashing lights going on but I don't the source of it. Please help me find this movie, I've been trying to track it down for years with no success.
