"I can't remember the last time I was able to see the sky..." In a broken society, a corrupt government rules, depriving its citizens of electricity and once common technology, imposing high taxes that plunge the nation into mass poverty, and slowly begin to whittle down the remainder of humanity. Underneath the nation's capital, scientists perform experiments unbeknownst to the public. Hoping to create the first bionic human weapon, officials abduct thirty children, robbing parents around the country of their only happiness. Among the thirty are twins Sage and Christopher Carter, whom are separated on arrival. Five years after her capture and the tortuous tests begin, Sage becomes desperate to escape the Chamber. Believing her brother dead, she plans to flee the day before her "graduation" but comes face to face with Aaron, an assassin belonging to what he calls the Legion. Seeing an opportunity in his outstretched hand, Sage follows, hoping to find light in this dark world.
