In the divided society of a mega city on its way to independence, police investigators are dragged into a series of dangerous events. A fight against the criminal organization threatening the city results in multiple deaths of people dear to Detective Frank Harris-most importantly, his wife. When Frank's only daughter returns home after a long year abroad, his colleague goes missing under disturbing circumstances. Jack was last seen in the majestic, modern city of Newbourne but now can't be located. Misled and distracted by different groups shamelessly fighting for power, Frank must rely on his guts and the kindness of strangers on his way to the Alter-City underground. Despite what he thought he knew, Frank soon realizes there is much more to his world than he imagined.
