Millennium

Bill Smith, chief investigator for the National Transportation Safety Board (NTSB), investigates the crash of an airplane with a great number of casualties. He meets the gorgeous and singular Louise Baltimore, who is a time traveler, in the hangar where he is examining the debris of the airplane and is immediately seduced by her. They have a one night stand and on the next morning, Louise tries to convince him to stay with her, but the reluctant Bill goes to the hangar. While snooping around in the debris, Bill is attacked by Louise, who does not seem to recognize him, and her friends. Bill soon learns that Louise is a time traveler from 1000 years in the future, when the population is sterile, and replaces the passengers from airplanes that will crash by corpses with the same features. However, they have to be careful to avoid time paradoxes that may destroy their world.
