In a vast, multicultural and decimated urban landscape, set after a financial collapse, Sawa, beautiful but emotionally detached young woman, lives a secret life as a covert assassin. The daughter of a police detective involved in the investigation of human trafficking, she was orphaned at the age of 12 when an unknown assailant targeted both of her parents. Now 18, Sawa is a human time-bomb intent upon eliminating members of the flesh-cartels whom she presumes murdered her family—men who exploit the defenseless children of a collapsed society for the pleasure of high-paying, foreign clients.
