Five years after killing her friend Tessa in self-defense, Star is guilted into a dangerous mission by Tessa's father to travel to the enemy-occupied planet, Dyanzia. The mission: to bring back someone infected with the same mind control device Tessa had in her brain. Accompanying Star is Tessa's younger sister Brianna who has not forgiven Star for what she did. As the two soldiers try to find a way to work together, they discover there is much more than mind-controlled Dyanzians on the planet.
