The world's two deadliest spies in the ultimate showdown. At a small-town carnival two men, each mysteriously summoned by telegram, witness a bizarre killing. The telegrams are signed Jason Bourne. Only they know Bourne's true identity and understand the telegram is really a message from Bourne's mortal enemy, Carlos, known also as the Jackal, the world's deadliest and most elusive terrorist. And furthermore, they know that the Jackal wants: a final confrontation with Bourne.

Now living a quiet life, nothing could lure Paul Janson back into the field. Nothing - except Peter Novack, a man who once saved Janson's life, who has been kidnapped by terrorists and is set to be executed. Janson hastily assembles a team of former colleagues and proteges to rescue Novak but the operation goes horribly wrong.

This time the stakes are higher than ever. For someone else has taken on the Bourne identity, a ruthless killer who must be stopped or the world will pay a devastating price. To succeed, the real Jason Bourne must maneuver through the dangerous labyrinth of international espionage, an exotic world filled with CIA plots, turncoat agents, and ever-shifting alliances, all the while hoping to find the truth behind his haunted memories and the answers to his own fragmented past.

His memory is blank. He only knows that he was flushed out of the Mediterranean Sea, his body riddled with bullets. There are a few clues. A frame of microfilm surgically implanted beneath the flesh of his hip. Evidence that plastic surgery has altered his face. Strange things that he says in his delirium -- maybe code words. Initials: "J.B." And a number on the film negative that leads to a Swiss bank account, a fortune of four million dollars, and, at last, a name: Jason Bourne.
