Bourne finds himself a target of a KGB killer, and is forced to come out of hiding once more to attempt to discover the truth about his past. He finds that he has been used for an unapproved assassination and there is a traitor in the American camp.
Lots of martial arts, gunfire, CIA people looking at TV screens and car chases.
A bit difficult to follow at times (the books were beyond me) but some great set pieces, and watch for the newspaper and the toaster, really clever. If anything a bit too much car chasing but great stuff if you like your heroes to be more or less invincible.
