Deputy Director Pamela Landy (Joan Allen) is brought in to help capture Bourne. With her help, Vosen and his team realize that Daniels was the source. They send a team to his office, but Bourne arrives first, defeating the CIA team when they come. While there, Nicky Parsons (Julia Stiles) turns up. Nicky tells him that Daniels fled to Tangier and helps him escape the CIA reinforcements. When Bourne asks Nicky why she is helping him, Nicky only hints vaguely to something Bourne has forgotten due to his amnesia. In Tangier, they realize that the CIA has sent assassin Desh Bouksani (Joey Ansah) for Daniels. Nicky uses her official clearance to send Desh a message, telling him to meet her for a new phone. This allows Bourne to follow Desh to his target. When Vosen realizes Nicky's deceit he orders Desh to kill Nicky and Bourne after Daniels. Landy is outraged at Vosen's willingness to indiscriminately kill CIA personnel and thus quits the operation.

Bourne follows Desh, but fails to prevent Daniels' death. When Desh returns for Nicky, Bourne outruns the Tangiers police and fights Desh, eventually strangling him with a towel. At the Tangier morgue, Bourne examines Daniels' charred papers and finds the address of the CIA substation in New York City. While Bourne journeys to the U.S., Nicky has no choice but to go into hiding. In New York City, Bourne calls Landy while observing her and Vosen from across the street. The ending of The Bourne Supremacy is repeated: Landy tells him his real name is David Webb and that he was born on "4/15/71", a code for the address of the Treadstone facility at 415 East 71st Street. Bourne sends a text message to Landy to arrange a meeting, and Vosen and his team, who have intercepted the message, follow as she leaves the building. This is actually a diversion, however, allowing Bourne to enter Vosen's office and steal classified Blackbriar documents.

Bourne's journey to the facility is delayed by a car chase with Paz, whom Bourne chooses not to kill, given the chance. Just outside the facility, Bourne meets Landy and gives her the stolen documents before entering the building. Inside, he meets Dr. Albert Hirsch (Albert Finney), who ran Treadstone's psychological conditioning. With his help, Bourne remembers that as Captain David Webb, he volunteered for the program. However, he tells Hirsch that he no longer wants to be Bourne or have anything to do with Treadstone and the CIA. Back at the substation, Vosen's team realize Landy gave Bourne an address in code. Vosen races to the facility and confronts Landy, but she has already faxed away his documents. Meanwhile, Bourne is cornered on the facility's rooftop. Paz holds Bourne at gunpoint and demands to know why Bourne spared him; Bourne's answer is, "You always have a choice," repeating the last sentence Marie spoke to him before dying in The Bourne Supremacy. Paz lowers his weapon as Bourne moves to escape, but Vosen appears and fires on Bourne just as he jumps from the roof into the river below.
