Elsewhere, emotions escalate when President Taylor learns of a larger looming threat that jeopardizes the peace accord with President Hassan. Also, Sergi Bazhaev, the Russian arms dealer, agrees to let his son, Josef, try to get medical treatment for his other son whom has radiation poisoning.
- Open with accounts that Hassan's forces are rounding up all those suspected of conspiring against his administration. Farhad calls one of the higher-ups back in Kamistan looking for money to pay Bazhaev. Despite the plan to kill his brother having failed, Farhad still believes they will be able to take control once they get their hands on the uranium rods.
Cut to Josef telling Bazhaev that he has found a doctor to treat his brother Oleg's sickness. Even though it's his own son, Bazhaev thinks the risk is too great. He does allow Josef to take Oleg to their country home where he will be more comfortable. Farhad tells Bazhaev he will have the money for him in five hours.
Walker and Jack cauterize the wound surrounding Ziya's missing thumb. Jack thinks she is unstable and wants to call off the mission.

While finishing Jack and Walker's cover story, Dana gets another call from Wade. He says if she's not home in a half hour he's going to tell Cole her real name and that she's been convicted of accessory to murder. Dana gets Arlo to cover for her and she takes off.

Dana arrives at her place to find Wade has a friend staying with him. She offers him $1,000 to get lost. Instead, he would like to take advantage of her job at CTU. He wants her to set him up with a six-figure score or he will destroy her life. If she does that, he says he will leave her alone.
Walker will have access to Jack's voice while meeting with Vladimir. As she walks in, Chloe tells Jack that Vladimir was "obsessed" with Walker and beat her number of times. He even tried to rape her.
During the meeting with Vladimir, Walker is able to answer all of his questions about her criminal connections in Mexico City. Despite having all the answers Vladimir isn't convinced and tosses Walker and Ziya into a trunk. Jack loses connection with Walker. With Chloe helping on surveillance, he follows a vehicle leaving Vladimir's compound. He's convinced Walker will be killed and wants a team scrambled.
Josef pulls a gun on a doctor, telling him he knows where his family lives and will harm them if he does not treat Oleg in secret. The doc thinks Oleg looks pretty sick and seems stunned to learn he was exposed to weapons-grade uranium.
Hastings has a team a few minutes away and Jack manages to convince him they must engage while Walker is still in the car. The mission is over. Jack then hears Walker being taken out of the car even though the vehicle they are following is still moving. A second car was snuck out the back and CTU is more than ten minutes behind. Jack tells Walker through her com to delay as long as possible. Vladimir puts both of them on their knees and asks what is really going on. Ziya sticks to the truth and is quickly shot in the head. Vladimir next points the gun at Walker, who all but begs him to kill her. She says this deal is the last thing she has in her life and without it she might as well be dead anyway. Vladimir puts away the gun and tells her "I had to be sure." Jack tells Hastings to call off his team: "She's in. They bought her cover."
