The Bourne Identity

In the Mediterranean Sea, Italian fishermen rescue an American adrift with two gunshot wounds in his back. They tend to his wounds and find he has no memory of his identity, but retains his speech, advanced combat skills and fluency in several languages. The skipper finds a laser projector under the man's hip that gives the number of a safe deposit box in Zürich. Upon landing in Imperia, Italy, the American goes to the bank in Switzerland to investigate the deposit box. He finds it contains money in various currencies, passports and identity cards with his picture on them, and a handgun. The man takes everything but the gun, using the name on the American passport, Jason Bourne.
