Wayne watches news reports of the nuclear blast, affected by what he is seeing. When Lennox comes in, Wayne is suspicious of his involvement in Karen's resignation. Lennox suggests that Karen quit because she knew she couldn't stop his new plan for the Administration. Wayne is resistant to sign Lennox's executive orders, knowing they will abuse power and civil liberties. Yet Lennox makes a strong argument and Wayne despairingly tells him to convene his cabinet.
Lennox lets Reed know that they have succeeded and that the President is ready to sign the order. "Getting rid of Karen was distinctly unpleasant, but she left us no choice," Lennox says.
Karen tells Buchanan that she resigned, but she refuses to tell him why. She abruptly hangs up on him, and when he calls her back Karen does not pick up the phone.

Graem goes to his house to erase all of his hard drives.
Captive in the van, Phillip wearily admits that everything he ever did was for Jack. Phillip only now realizes that he pushed him away. After Jack left, Graem was all he had left.
After arriving at a cement plant, Jack and Phillip are lead out in handcuffs. Phillip offers the men double whatever Graem is paying them, but they don't accept. Phillip refuses to get on his knees at a freshly dug grave. With the men distracted, Jack is able to wrestle one of their guns with his locked hands. He shoots both men. Phillip grabs the keys and releases the handcuffs.
Jack uses the dead man's cell to call Buchanan. He lets him know that his brother lied to him and tried to have him killed. Buchanan sends a field team to Graem's mansion. Jack wants Burke the torture specialist brought in too.
McCarthy phones Fayed because he has found someone to program the triggers for the bombs. McCarthy emails Fayed the engineer's photo and background. "He'll need to be coerced," McCarthy warns.
Fayed's call is intercepted by the feds, and the CTU team hears McCarthy notifying Fayed about someone to detonate the nuclear weapons. Morris attempts to salvage an image file that McCarthy sent to Fayed of the engineer.
Jack meets up with the field team outside Graem's mansion. Although Phillip wants to go with him, Jack says he will need to question Graem alone and do "whatever it takes to find out what he knows."
While Graem works feverishly on his laptop, he lies to Marilyn about what's going on. Suddenly, the CTU teams raid the house. Graem pulls out his gun, but he is surrounded. Jack and Graem are locked in a standoff, but Graem gives up his weapon. Jack has an agent upload all computer hard drives to CTU.
Jack drags an angry Marilyn into another room. She doesn't believe that Graem would try to have Jack and Phillip killed. He tells her about Graem's involvement with the nuclear bombs. While she believes that her husband is capable of such things, Marilyn does not know about any of his dealings. Jack promises to look after both her and Josh, but Marilyn only wants to leave. "I've seen what happens when you try to protect people," she shouts. Jack orders for Marilyn and Josh to be transported to CTU.
Outside the house, Marilyn sees Phillip and asks him if what Jack said about Graem is true. She takes Phillip's silence as confirmation.
As Agent Burke sets up a camera to monitor body temperature, Graem claims to Jack that he doesn't know where McCarthy is. Burke sees that Graem is lying about something. Jack calls for Burke to bring in the interrogation setup.
Milo lets Chloe know that Morris's brother was exposed to radiation and is in critical condition. Milo wants to keep this from Morris, but Chloe disagrees.
Chloe brings Morris the bad news. Morris is confused because his brother wasn't supposed to be in Valencia. He tries calling the hospital but cannot get through.
With no information on his dying brother, Morris gets up to leave. Chloe convinces him to stay and finish decrypting the photo that was sent to Fayed.
Jack checks in with Buchanan and learns that Fayed found an engineer to detonate the nukes. Jack realizes his time is running out, and he presses Graem to tell the truth. Burke prepares a syringe of hyocine-pentothal to induce pain, but Graem still claims that he doesn't know McCarthy's whereabouts. Graem is injected with a small amount and winces in agony. Jack is disturbed to see his brother go through this torture.
Jack clutches Graem's head and begs him to give up what he knows and forestall any more pain. When Graem offers nothing, Jack has the levels of serum increased. Graem launches into a series of spasms and Jack holds him tight for comfort.
When Graem is still tight-lipped, Jack urges Burke to go even higher with the IV. This prompts Graem to confess that he arranged for the assassinations of David Palmer, Tony Almeida and Michelle Dessler. He even arranged it so that Jack would come out of hiding to take the fall. "Today wasn't the first time I've tried to have you killed, Jack," Graem says with spiteful pride. Jack reacts in heartbroken disbelief.
Graem claims his actions were for his country, and he says that the two of them are the same. "We are not the same!" Jack yells in rage before throwing back Graem's chair. He charges Burke at gunpoint to increase the serum to a deadly level and then threatens to kill Graem. As Jack points his gun at Graem's temple, he looks up and sees his father in the doorway. Jack suddenly stops in his tracks. He has Burke shut down the IV drip on Graem and walks away in silence.
Lying in a hospital bed, Walid conveys to Sandra that he is ashamed for spying on the innocent men in the prison. She gets a call from Wayne, who apologizes for what happened to Walid. Sandra tells him that the inmates only saw the information on the internet. Wayne's administration is detaining people who might be able to help, but they are afraid to come forward because they will be imprisoned or deported.
Distracted, Morris is unable to make the image clearer. He downloads an unlicensed hack to help further the task.

From the airborne cabin of Air Force Two, Vice President Noah Daniels congratulates Lennox about the plan he has pushed through. "To be honest, I didn't think this President had the stomach for the cure," Daniels growls.
Lennox puts Daniels on speaker phone as Wayne enters the bunker conference room. It is filled with generals, cabinet members and advisors. Wayne explains to the group that Lennox's plan sacrifices rights and freedoms granted by the Constitution. To implement it would be a mistake. Lennox argues his case, but Wayne is insistent that the American Muslim community is the country's best line of defense. Daniels suggests the President hear from some other sources, but Wayne stands firmly by his decision.
As the image materializes, everyone at CTU is shocked when Morris's face and resume is revealed. Buchanan orders an APB on Morris's car and he tells Jack what has occurred.

Jack boards the helicopter.
At the mansion, Burke allows Phillip to speak to Graem in private. Graem is proud of himself for taking whatever Jack did to him and not revealing Phillip's involvement in the plot. He assures his father that he won't tell Jack anything, no matter how much worse the interrogation gets. They successfully convinced Jack that Phillip was innocent. Their plan is for Graem to take the rap and for Phillip to get him released in time. "The company lives on," Graem says.
Despite Graem's confidence, Phillip isn't so sure that his son will hold firm. Graem tells Phillip that he loves him, and Phillip returns the compliment. Then Phillip apologizes and injects Graem's IV with a full dose of hyocine-pentothal. As Graem convulses, Phillip covers his mouth so no sound can escape. Graem's body goes limp, and Phillip kisses him on the head.
Phillip bellows that his son has had a seizure. Burke and the other agents try to revive Graem. "If you people kill my son, I swear you're gonna regret it for the rest of your life," Phillip threatens.
