Life in Unitus (formerly the United States) is so unbearable that 15-year-old Abby Byrd sees only one way out: alien abduction. She succeeds in attracting an alien, but instead of a friendly rescue, the alien warrior has murder in mind. Abby manages to steal his ship, but damages it in the process. She elicits help from the twin boys with whom she has a complicated relationship: she likes Lucas, but Logan likes her. Meanwhile, both the alien warrior and agents from Unitus are closing in on Abby and her spaceship--and the alien's teenage nephew, knowing his uncle's violent nature, shows up to prevent him from killing anyone. He and Abby are immediately attracted to each other, but the twins are jealous and Unitus is going all out to thwart any threat to its power--alien or human.
