While at a meeting at CTU, ex-agent Jack Bauer tries to stop a second terrorist attack after learning the terrorists' next target is his new boss, U.S. Secretary of Defense James Heller.

Chloe secretly helps Jack, who goes to desperate lengths as he follows the terrorists hoping they will lead him to Heller. Heller's son, Richard, is brought into CTU for interrogation.

As Jack follows the terrorist, President Keller is presented with a drastic alternative even as Heller and Audrey decide to foil the terrorists' plans by taking their fate into their own hands.

Edgar tries to thwart the terrorists by taking the vulnerable power plants offline, Jack and Audrey are ambushed, and Dina Araz tries to save Behrooz after he says they should go to the police.

While Behrooz goes to get pain medication for his mother, Jack and Tony capture Dina and promise her that Behrooz will go free if she helps them find the override device.

CTU learns that a man named Marwan is behind the attacks, Audrey's husband, Paul, agrees to help Jack, and Driscoll has to deal with her increasingly angry and unstable daughter.

Jack and Paul find themselves the target of a search-and-destroy mission, Tony is stunned when Michelle shows up as Driscoll's replacement, and Marwan launches the next phase of his plan.

"Fearing that information about a murdered U.S. Air Force family may arouse CTU's suspicions, Marwan creates a diversion by calling Michelle and offering to trade Jack for Behrooz."

After Air Force One is shot down in the desert, Jack's only hope of keeping the nuclear football out of the hands of the terrorists comes from two campers who saw the plane go down.

After President Logan botches up CTU's capture of Marwan, he agrees to call in an advisor who has dealt with terrorism firsthand, and Chloe's first field assignment almost ends in disaster.

As CTU tries to hold off retaliation from the Chinese Consulate and President Logan braces for a political backlash, Jack and his team head to the factory where Marwan is hiding.

As the Chinese secretly launch their own kidnapping, Tony falls into the terrorists' hands, and any hope of shooting down the armed warhead in time grows more and more remote.
