Jack cleans up the remains from the smashed syringes in his office. He finds one vial of heroin that was not destroyed. He places it back into his medical kit.
Tony and his team brief White House Chief of Staff Wayne Palmer on the terrorist's demands. Dr. Macer from National Health Services is also on the teleconference, and she conveys the severity of the situation. This leaked virus is a strain that Health Services has never seen before because it has been engineered to kill ten times faster. Wayne reiterates the President's policy of standing firm against terrorists. Wayne knows that Palmer will not free Salazar, regardless of the threat.
Kim calls her father to remind him that she needs to speak to him about something personal. Jack promises he will come down to see her when he has more time. Chase notices that Jack did not shoot up the heroin. Jack admits that he has been tapering off his usage and will now stop. Chase doesn't think this is a good day for him to need a fix, and he suggests a methadone program. Jack refuses to go on record with his addiction. He orders Chase to get back to work.
Chloe asks Chase about what she overheard on the teleconference. She's worried about a possible outbreak in a few hours. He asks about the list of the drug dealer David Goss' associates. Chloe says that Kim will be bringing the information shortly.
Kim comes up to the Field Ops area to give Chase the list. He asks why she insists on telling Jack about their secret today. Jack harbors doubts that a Field Agent could ever sustain a relationship. As Chase watches, Kim enters Jack's office. She confesses to her father that she and Chase have been seriously dating. Jack is thrown by the news, but doesn't let on to his concern. She leaves, telling Chase that Jack had nothing to say.
Dr. Macer calls Michelle with an update on Goss' autopsy. The virus may have been transmitted in crystalline form, which means that the delivery mechanism is a white powder that could resemble cocaine or heroin.
Kyle tries to persuade his friend Tim to accompany him in the drug delivery, but Tim refuses. Kyle gets a call from a guy named Zach who orders him to drop off the cocaine at 7:30. Kyle nervously agrees.
Michelle notifies Jack that she found the last known address for Goss. He grabs Chase and they pull guns from the cabinet. Tony orders Michelle to place transmitters onto Jack and Chase so that CTU can monitor their movements. Michelle hands Jack the Goss file. Kim brings over a medical kit to ward against the virus. "Be careful," she says to Chase as he follows Jack out.
Outside CTU, Jack and Chase get in the SUV. Chase confirms for Jack that things are getting serious with Kim. Jack eyes his partner warily. There's tension as they drive away.
At the University of Southern California campus, Palmer questions whether he should proceed with the debate in the face of a virus threat. Wayne notes that CTU and the Pentagon are working on it and that the President can only wait. Palmer wants assurances that Wayne is not advising him out of fear that his campaign image will suffer. Wayne thinks the best thing to do is proceed with the debate and respond when they have more information. Senator Keeler arrives and Palmer shakes his opponent's hand in front of the media. The President spots Wayne having a talk with one of Keeler's staff. Wayne later tells Palmer that he may have found an "opportunity."
After a silence, Chase initiates a talk with Jack about the Kim situation. Jack only placed his daughter at CTU to keep her safe. Jack feels that his job has ruined every relationship he's ever had. Chase concedes that it's not the job, but Jack himself who is the problem. Jack thinks Chase won't be able to have a relationship with anyone, especially Kim. Jack gets a call from Annicon who questions why Salazar can not be moved from the prison. Jack lets the lawyer know that there is a possibility that Salazar might be released because of leverage from Hector Salazar. Jack won't reveal any more, and hangs up. He tells Chase that they will continue their conversation later.
Annicon enters Ramon Salazar's cell and asks about his brother Hector's activities. Salazar plays dumb. Salazar smugly mentions that if he's allowed to go free, he will kill Annicon's wife and children. Annicon lunges at the prisoner in anger.
Wayne checks in with Tony, and then informs Palmer that CTU is following their leads. The new suspect is Hector Salazar, but they are still unaware if this is a bluff to release Ramon Salazar. Palmer asks about the "opportunity" they spoke of earlier. Wayne might be able to get Keeler's playbook that outlines how he will answer questions in the debate. "I am not talking about pulling a Sherry and stealing it," Wayne snarls when his brother questions his ruthless tactics. Palmer makes it clear that he doesn't want Wayne to go that far.
In the restroom at CTU, Kim asks Michelle if it has been a problem working with her husband in the office. She has been dating Chase, and Jack seems to be bothered by this. Michelle advises Kim to keep it between herself and Chase. Michelle leaves the ladies room and Tony stops her. They have learned that Hector may be working out of Northern Mexico. Tony wants her to alert all of CTU's contacts to see if he's been spotted there.
Hector calls Gael from his Los Nieves ranch in Northern Mexico. Gael knows that the President has already been informed but has not cancelled the debate. Hector spots Claudia arguing with her father, the ranch foreman. Claudia's father is worried about her involvement with Hector's illegal activities. Hector yells at Claudia for raising her voice to her father, and then he slaps Claudia in front of him. She slaps him back without missing a beat. "How I conduct myself with my father is my concern," she tells him. Hector smiles and kisses her.
Chloe informs Tony that Jack and Chase have arrived at the location, but that Jack doesn't have time to wire up the transmitters. Tony demands that Chloe keep him apprised of any information from Field Ops. Chloe reluctantly obliges.
Jack and Chase approach a plainclothes officer who debriefs them on the activity inside the condemned building where Goss is known to reside. There are a number of people inside this crack den. The police have been ordered to stand down and wait for CTU. Jack and Chase will go in by themselves without backup so as not to set off any warnings.
Jack and Chase go inside the building and pass rooms filled with people taking drugs. They are stopped by a guy who alerts the others that a cop is on the premises. Zach, the guy waiting for Kyle's delivery, shoots at Jack and Chase. They fire back and Zach runs away. Jack pursues Zach through the empty building and wounds him. Zach falls to the ground, bleeding. He confesses to Jack that Goss' supplier is Carlos Corretja from Tijuana. Corretja is one of Salazar's mid-level distributors. Zach is supposed to call Corretja that night after his hired mule brings a small bag of cocaine across the border. What is strange is that the guy was paid $10,000 to transport it up, and the cocaine isn't even worth that much. Zach says that the mule named Kyle Singer still has the bag.
Kyle hands cash to his building landlord to prevent his family from getting evicted. His mother wants to know where he got the money. Inside the apartment, Kyle's girlfriend sees the bag of cocaine in his room.
Tony instructs the CTU staff to investigate Kyle Singer based on Jack's findings.
Kyle's girlfriend Linda confronts him about dealing drugs. He tells her that he is only delivering it to make money for his family. Linda breaks up with him and walks out. Kyle's mother says that his father won't be happy about what he's doing.
Palmer stops in to see Anne. He is having her security level upgraded because he needs her medical advice. After he informs her of the virus that might be spread, she warns him to leave Los Angeles. Palmer asks that she speak to Dr. Macer and bring herself up to speed. They embrace. Agent Pierce comes in to notify the President that Wayne would like to show him something.
Jack instructs Chase to take Zach back to CTU, but Chase wants to go with Jack to find Kyle Singer. "Are you punishing me for dating your daughter?" Chase asks. Jack says that he now has to prevent Chase from being in harm's way because Kim loves him. Chase is dumbfounded as Jack drives off.
Wayne shows his brother the copy of Keeler's playbook. Palmer is furious, but Wayne tells him there are things in there about Anne that they were not aware of. This information could damage them all.
Hector calls his informant Gael, who updates him that Kyle is still in the house with the cocaine. Gael pulls up surveillance footage of the CTU office on his monitor. He exits the room he is in to enter the CTU main floor. Kim approaches him and tells him that Chloe has been looking for him. Gael, a worker at CTU, goes to find her.
