Badly wounded and suffering from amnesia, Jason Bourne (Matt Damon) is pulled out of the Mediterranean by fishermen, and is able to recall neither who he is nor what happened to him. His only clue to his identity is the number of a Swiss bank account which has been etched into a device implanted in his body. Following the lead to Zurich, he discovers money, passports and a gun waiting for him, but also earns the attention of the security services and has to leave in a hurry. He then persuades a young woman named Marie Kreutz (Franka Potente) to drive him to Paris, where he hopes to find out his true identity and discover the reason why the CIA are taking such an interest in him. Directed by Doug Liman ('Swingers', 'Go').
