This is a horror themed one as a pretty young woman is walking home and is being chased by a prowler. She runs all the way home and locks the door behind her. She turns turns around to reveal that she's none other than actress/singer Adrienne Barbeau, who was best known at the time for her roles in science fiction/horror movies such as "The Fog", "Swamp Thing", "Creepshow", and "Escape From New York".
