I remember seeing this movie on TV around 1997. Two ladies (I remember one was married with children)  go out on the town to celebrate. They were abducted by a deranged man who was stalking one of them. I think he felt rejected by one of them. I believe he bumped into her once, and she apologized, and he said, “Pretty lady like you should never be sorry.” He put them in the trunk of his car and actually filtered carbon monoxide into the trunk. When they tried to push the carbon monoxide out, he started sticking a knife through the trunk. Anyway, I believe one of them survived. She continued to speak at his parole hearings. When his parole was denied, he said, “It’s not over.” And that’s where the movie ended. Does this sound familiar?
