Shadow - the head of Treadstone - has found evidence of massive Chinese espionage activity in the U.S. The spy running the operations is a shadowy American known only by the codename Bai Ze. No one knows who he is, but when Shadow consults the Files - the hacked AI database she stole from the Chinese - she discovers that Jason Bourne encountered Bai Ze during an operation eight years earlier. The trouble is, Bourne doesn't remember him. As Bourne hunts for the elusive spy, he meets a reporter named Laney Reese who shares his strange affliction: eight years ago, Laney lost her entire memory, too. For Bourne, that can't be a coincidence. He's convinced that whatever happened to both of them is at the heart of the Chinese espionage operation. With Laney at his side, Bourne follows a zigzagging trail of clues to a quirky billionaire and his ex-wife, both of whom may have ties to Bai Ze. As he gets closer to his shadowy adversary, Bourne begins to suspect that he's walking into a trap. But it's a trap with an almost irresistible bait - the chance to recover his forgotten memories. Now Bourne must decide how far he'll go to get his life back.
