After a comet releases a mysterious virus that begins to kill all of the women in the world, a young couple's relationship is severely tested. They hide out (from both the illness and the savages who hunt the remaining women) in their over-sterilized apartment. Ultimately the duo escapes their self-imposed quarantine to head to the wilderness.

16-year-old Cassie Sullivan tries to survive in a world devastated by the waves of an alien invasion that has already decimated the population and knocked mankind back to the Stone Age.
