Wounded to the brink of death and suffering from amnesia, Jason Bourne is rescued at sea by a fisherman. With nothing to go on but a Swiss bank account number, he starts to reconstruct his life, but finds that many people he encounters want him dead. However, Bourne realizes that he has the combat and mental skills of a world-class spy—but who does he work for?

After his friend, a hot young artist, is killed, a resourceful American man living in London covers up the crime and tries to keep the friend's name alive in order to exploit his legacy and reap millions in the process.
