Spoilers for this episode.
Chloe decrypts a lead from Henderson's computer linking intelligence broker Collette Stenger to Bierko. Jack and Curtis search her hotel, where Theo Stoller ambushes Curtis before identifying himself as a German intelligence officer. He refuses to surrender Collette because his undercover work reaches beyond the immediate American threat. Jack offers the WET list of suspected terrorists in exchange for help arresting her, and Chloe obtains the file despite Homeland Security's restrictions.
Collette sells Bierko the plans for a gas distribution facility before meeting Theo at the airport. Theo leads her into Jack's trap, and CTU takes her into custody. The transferred memory card, programmed to self-destruct, destroys the list when Theo attempts to upload it, leaving him furious that their bargain was a deception. Collette demands immunity before identifying her source. When the agreement arrives, she names Audrey Raines as the person who supplied the schematics, an accusation Jack refuses to believe.
Logan announces an immediate military curfew over Martha's objections. Karen Hayes and Miles Papazian arrive at CTU to assess its operations while preparing to absorb the unit into Homeland Security. Wayne Palmer asks Aaron Pierce for a private meeting about his brother, but his journey to the presidential retreat is interrupted after he clears a checkpoint. Armed men force his car off the road, and Wayne flees on foot before they can capture him.
