In this movie this woman works in some high security building. There is a buff security guard that is obsessed with her. The security guard has cameras everywhere. The security guard gets upset when he sees the woman making out with her boyfriend in the parking lot. The security guard then traps the woman and her boyfriend in the building. Most of the movie is just cat and mouse with them trying to escape. She finally is able to break the glass but he threatens to kill her boyfriend. Does this sound familiar?  I want to say that I saw it on TV in the late 90’s.
