Thirty-three has no past—at least none that she can remember. Raised by the Institute from infancy she has been through hell and back due to a training incident that took her limbs and almost killed her. Paired with her cybernetic tiger, Belle, Thirty-three is selected to eliminate the terrorist, Dominic Durant, and his men, and regain control of the refueling station on the planet Zahiria. Things go awry when instead of following orders meekly, she retaliates against the one man she hates most.
