Jason Bourne is known and feared in the deadly world of covert-ops as one of the most highly skilled assassins for hire. Bourne, however, was merely an identity assumed by CIA agent David Webb, a personality implanted by the CIA to facilitate a dangerous operation. Years later, Webb is no longer an active agent; he's now a professor at Georgetown, living a quiet life. Until one day he finds himself the target of an assassin nearly as skilled as himself and is framed for the murder of his two closest associates and friends. As he fights for his life against unseen assailants, as well as the full resources of the CIA, who believe he has gone dangerously rogue, the Bourne identity reasserts itself, leaving Jason Bourne in control.
