Summary

• A mole is revealed to be working inside CTU, aiding the terrorists.
• The bombing of a commuter train which allows the theft of a device known as the Dobsen-type Override which could be used to take control of (and meltdown) United States nuclear power plants.
• The kidnapping of Secretary of Defense James Heller and Audrey Raines which is broadcast over the Internet. Both hostages were rescued by CTU before their executions could take place.
  • the use of the override requires a surge in Internet traffic, presumably to overcome security at nuclear plants nationwide, as the attempt is masked by the Internet chaos caused by the mass streaming of videos regarding the kidnapping of the Secretary of Defense and his near-execution.
• The override being used, causing a meltdown in the San Gabriel Island reactor. This distracts CTU director Erin Driscoll from checking on her mentally ill daughter, who commits suicide. In an effort to cover-up their complicity and erase computer records, the defense contractor that developed the override activates an EMP that also causes a blackout over an 8-square-mile (21 km²) section of downtown Los Angeles.
• The resulting turmoil from the near-meltdown and EMP allows a stealth fighter to be stolen from an Air Force base in Southern California. The stolen stealth fighter shoots down Air Force One, which crashes into the Mojave Desert, almost killing President Keeler in the process and elevating the Vice-President Charles Logan under the 25th Amendment. Terrorists attempt to steal the nuclear football from the Air Force One crash site.
• A nuclear warhead in Iowa is purloined and fired at Los Angeles before its nuclear code can be deactivated.
• A Chinese national at the Chinese Consulate in Los Angeles is revealed to be complicit and is captured by CTU. In the process, the Chinese Consul is killed by friendly fire (the American agents never fired a shot during the mission), leading to a serious diplomatic problem with China. The Chinese government begins investigating the raid at the Chinese Consulate and begins to suspect CTU's involvement.
  • Logan's administration attempts to frame Jack Bauer as acting against authorization by the US Government. David Palmer warns Jack that someone in the administration is trying to have Jack conveniently killed, causing Jack to perform a pseudocide with four conspirators: Palmer, Michelle Dessler, Tony Almeida, and Chloe O'Brian.

A few plot points can be seen as an a homage to the James Bond film "Thunderball" including Mandy's efforts leading to the theft of the pilot's identity which lead to stealing a fighter jet, and the theft of a nuclear missile.
