It´s been over a decade since Nash Rollins recruited a brilliant, talented, but disaffected young man named David Webb to join Treadstone. Webb became the agent known as Cain-and later took on the identity of Jason Bourne. That violent winter-which included Cain´s first mission for Treadstone-was also a story of betrayal in ways that David never knew. So after the injury that erased Bourne´s whole life, Nash lied about the circumstances of David´s recruitment to Treadstone. He was afraid that learning the truth might drive Bourne out of the agency forever. But now, when Bourne meets a woman who recognises him as David Webb, the secrets of those days begin to come out-and Bourne is forced to confront the dangerous ghosts of a past he doesn´t even remember.
