The Bourne Identity (2002)

A man is found floating in the Mediterranean Sea. When the ship's doctor examines the unconscious castaway, he discovers two bullet wounds and an implanted device that displays a bank account number. The amnesiac Bourne travels to Zurich and gains access to a safe-deposit box containing a gun, thousands of dollars and valid passports from numerous countries--each listing a different identity. Within minutes, Bourne is on the run from a seemingly ever-present agency, relying on language and fighting skills he didn't even know he possessed.
