When Jacob Fields, a former CIA agent, returns after being presumed dead for two years, he kills his best friend first. His reasons for his actions are unknown. Kathryn Madison, the CIA's best agent, is put on the case to pursue this unknown factor.

But not everything is as it seems. Madison's loyalties become strained, and she is unable to decide who to trust, not even her fellow agents, as a conspiracy is uncovered that could ignite a war.

Loyalties change, allies become enemies. Only a handful of loyal patriots stand between fragile peace and all-out world war.
