Jason Bourne pulls a drowning man from a lake - a man not only freezing, but bleeding profusely from a gun-shot wound. He wakes as an amnesiac, with no memory of who he is or why he was shot...an eerie reminder of Bourne's own past.
Meanwhile, Mossad agent Rebekah is so determined to find this man that she's gone off the grid, cut her ties to her agency, and risks a summary execution if caught by her former colleagues. And back in the U.S., a new agent has been recruited - but does he have a secret mission of his own?
Everything turns on the mysterious amnesiac. Will Bourne learn his identity or will other, powerful forces get to him first?
