Jason Bourne returns to Georgetown University, and the mild world of his alter ego, David Webb, hoping for normality. But, after so many adrenaline-soaked years of risking his life, Bourne finds himself chafing under the quiet life of a linguistics professor. Aware of his frustrations, his academic mentor, Professor Spector, asks for help investigating the murder of a former student. The young man died carrying information about a group's terrorist activities, including an immediate plan to attack the United States. The organization, the Black Legion, and its plot have also popped up on the radar of the Central Intelligence Agency, whose new director Veronica Hart is struggling to assert her authority. Sensing an opportunity to take control of the CIA by showing Hart's incompetence, National Security Agency operatives attempt to accomplish what the CIA never could do, hunt down and kill Jason Bourne. In Europe, Bourne's investigation into the Black Legion turns into one of the deadliest and most tangled operations of his double life—while an assassin is getting closer by the minute.
