As Adam watches Tony's movement on satellite, Jack follows the car.
Jane realizes that she is not being taken to Division, and Tony finally admits that he has kidnapped her in order to get his wife back from Saunders. Suddenly, another SUV swerves into Tony's car and forces him to a halt. Jack pops out of the SUV and draws his gun. He knows that Tony only wants to save Michelle, and he understands what he is going through. Tony's renegade actions are reminiscent of Jack's past deeds. Yet Jack needs Jane to lure Saunders, and he promises that Michelle won't suffer. Tony explains that Saunders directed him to a public payphone where he will receive further instructions.
Wayne thinks that the White House should release a statement about the exact nature of the threat. Palmer would rather withhold the truth than cause a widespread panic.
Senator Keeler comes to see the President. He accuses Palmer of lying to the police about Alan Milliken's death, and he shows him photographs of the medicine bottle kept from Milliken when he died. Sherry's fingerprints on the bottle will incriminate the President. Keeler calls for Palmer's resignation once the terrorist threat is resolved. He will allow Palmer to offer whatever face-saving reason he wants to give. Palmer orders Keeler out of his office.
Arriving at the phone booth, Jack orders Tony to reject the location Saunders chooses. Making him pick a secondary location will allow Chase time to get a team in place. Tony goes to the phone.
Jack listens in as Tony takes Saunders's phone call. Saunders gives Tony a location to deliver Jane, but Tony claims that area is in a CTU satellite area. Saunders refuses to change, and Jack hangs up the phone. Tony is furious, but Jack knows that Saunders will call back because he is desperate to get his daughter. Tony accuses Jack of jeopardizing Michelle because she would merely be an acceptable loss. "Didn't you learn anything from what happened to Teri?" Tony asks. Jack angrily pushes Tony. Suddenly, the payphone rings and Tony answers it. Saunders offers up a new location.

Chloe tells Kim that Chase won't leave Field Ops to start a family with her. He's too much like Jack. Kim brushes her warning aside.

As they head to the bridge, Jack calls Chase to give him a plan of attack. Jane asks Jack if her father will really kill innocent Americans with the virus. Jack explains that Saunders thinks the country betrayed him even though his job required him to make impossible sacrifices.
Michelle screams from the holding cell. Saunders's henchman comes in to find her with a bloody nose. He's frightened when Michelle says that she has contracted the deadly virus. The man radios Saunders, but Michelle knocks the guy out with a brick. She had bloodied her own nose to scare him. Michelle grabs his gun and cell phone, and runs off. Saunders goes after her.
Michelle can't get any service on the phone in the underground fortress. She finds her way to daylight, but hits a fenced-in dead end. Michelle calls CTU, but Chloe can't hear her. There's only static. Chloe hangs up.

As Chase's team lies in wait at the bridge, Tony asks Jack to do what he can to save his wife. The convoy carrying Michelle arrives at the spot where Tony is with Jane.

Saunders gets out of one of the cars to show himself to her. The SWAT team opens fire, as does Tony.
Saunders is shocked to see his plan backfire, and he runs into a riverbed toward a waiting helicopter. Jack takes off after him, but is fired at by the men in the chopper. Jack calls in for air support.
The Marines arrive in F-18 fighter jets, firing missiles at the helicopter. It explodes, and sends Saunders blown backwards by the blast.
Jane watches as Tony reunites with Michelle.
Amid the wreckage of the helicopter, Jack pulls his weapon on Saunders and demands to know where the other unaccounted vials of the virus are. "You can waste time trying to break me and kill millions of people," Saunders says to Jack. "Or you can give me what I want."
