Itsy Levan is devastated by her parents' decision to leave the city and buy a fixer-upper in the middle of nowhere. Her life seems over until she meets her space-obsessed neighbor Calvin Kipler, who believes that his parents were abducted by aliens 10 years ago on the night Jesper's comet was seen. Itsy sees this as her chance to get into a New York City journalism program by writing an exposé on Calvin, but she ends up discovering much more than what's on the other end of the comet's tail.
