Plot
The Earth is passing through the tail of a comet, an event which has not occurred in 65 million years and coincided with the extinction event that wiped out the dinosaurs. On the night of the comet's passage, eleven days before Christmas, large crowds gather outside to watch and celebrate.
Eighteen-year-old Regina "Reggie" Belmont works at a movie theater in southern California. She is annoyed to find the initials DMK have the sixth highest score on the theater's Tempest video game; all the other high scores are hers. Staying after the theater closes, she helps her boyfriend, projectionist Larry, sneak back in so he can loan out a film reel for illegal duplication for his own profit. He offers to pay for her assistance from what he expects to earn when the other party returns the film reel in the morning. Reggie and Larry spend the night in the steel-lined projection booth and have sex.
Meanwhile, Reggie's 16-year-old sister Samantha ("Sam") argues with their stepmother Doris, who Sam implies is cheating on her father, who is away on active military duty. After this escalates to a physical altercation, Sam spends the night in a steel backyard shed.
