CTU agents find Henderson's car, and Chloe was able to find information on Henderson's computer about an intelligence broker named Collette Stenger. President Logan holds a news conference, at which he announces that he is declaring a curfew that will be enforced by the military. Bierko plans to kill 200,000 people by releasing the nerve gas at a distribution center. Hayes tells Buchanan that CTU is being absorbed by the Department of Homeland Security.
Wayne Palmer calls Aaron and tells him he wants to meet him within the hour, and to keep it quiet. Aaron agrees.
Meanwhile, Theo Stoller, a German Federal Intelligence agent, attacks Curtis and points a gun at him asking who he is. After he shows him his ID as a federal agent, he tells them of his undercover operation to arrest Collette. Stoller's government refuses cooperation. Jack offers the NSA's highly fied "wet list" of known terror suspects in exchange for the German agent's help. Chloe hacks into the NSA computer and uploads the information to Jack's cell phone. Meanwhile, Stenger arranges to have $10,000,000 transferred to her Cayman Islands bank account. She gives Bierko the USB drive containing the schematics to an as-yet-unknown building and helps decrypt the data. Back at CTU, Chloe's hacking is discovered, and she tells Hayes and Buchanan what Jack wanted her to do. They are angry and shocked, and demand that Jack get the wet list back. Jack refuses, saying that the list will help prevent the attacks. Hayes warns of a fallout.
Wayne Palmer is stopped at a roadblock to the compound, but is let through after getting authority from the Vice President.
Jack and Stoller's operation is a success. They arrest Collette and handcuff her to a steel cage in an airplane hanger, telling her Stoller was a German agent who gave her up. However, the memory card containing the wet list self destructs. In effect, Jack and CTU get Stenger, but a list-less Stoller feels betrayed for giving up Collette for nothing, although Jack tells him he will try to get something of value for Stenger someday. Collette wants full immunity for her information. Jack calls CTU and tells Hayes what Collette wants. Jack then tells Hayes that he rigged the memory card to self destruct.
Unknown mask-wearing individuals run Wayne Palmer off the road. Palmer survives and immediately runs away from the scene being pursued by gunmen, as Aaron waits for his arrival at the compound. Meanwhile, Collette demands full immunity in exchange for the source of the schematics that she sold to Bierko. The government agrees, and Collette tells Jack that someone in the DOD gave her the information-Audrey Raines. Jack is left to wonder if Audrey is a mole.
