The fourth installment of the Not-So-Distant Future Series features major political upheaval at home and abroad. Battles between various gangs escalate in frequency and intensity, as the international gang Diablo attempts to eliminate competition and corner the market on a new weapon. As Chicago FBI field office leader Kerry O'Malley and her team investigate, they discover direct links between this weapon and Corbin Setag's failed plan to distribute a mind-control substance to the general population. Michael Kovanov, a rising leader of the Russian crime organization Shishka, is tied to the kidnapping of a US Senator who championed a controversial bill. Meanwhile, the Group is covertly struggling to prevent a world war, and Kerry is recruited onto an elite team that travels abroad to rescue the Senator and circumvent the Shishka's plans. As the world is embroiled in instability, and as her team narrowly escapes disaster, Kerry learns game-changing information about the nature of the Group.
