The story of a man (Matt Damon), salvaged, near death, from the ocean by an Italian fishing boat. When he recuperates, the man suffers from total amnesia, without identity or background ... except for a range of extraordinary talents in fighting, linguistic skills and self-defense that speak of a dangerous past. He sets out on a desperate search-assisted by the initially rebellious Marie to discover who he really is, and why he's being lethally pursued by assassins. In the Bourne supremacy, Jason Bourne tries to leave his violent life behind, and live a normal life, but his plans are crushed when he narrowly escapes an assassination attempt.
