Plot

In the Mediterranean Sea, Italian fishermen rescue an American man adrift with two gunshot wounds in his back. They tend to his wounds and find he has no memory of his identity, but demonstrates advanced combat skills and fluency in several languages. They find a tiny laser projector under his skin in his hip that gives the number of a safe deposit box in Zürich, and the man decides to go investigate. He goes to the bank to investigate the deposit box where he finds various currencies, passports and IDs with different names, and a handgun. The man takes everything but the gun, and starts using the name on the American passport, Jason Bourne. After Bourne's departure, a bank employee contacts Operation Treadstone, a CIA black ops program. Treadstone's head, Conklin, issues alerts to police to capture Bourne and assigns three agents to kill him: Castel, Manheim, and the Professor.
