Agent Jack Bauer, having been taken prisoner by China 20 months earlier, is released under a deal arranged by President Wayne Palmer. Jack is immediately asked to sacrifice himself to Abu Fayed, who has offered CTU Hamri Al-Assad, who is believed to be the terrorist mastermind behind the suicide bombings of the last 11 weeks. Jack finds out, however, that Assad is actually trying to stop the attacks, which were orchestrated by Fayed. Jack escapes and saves Assad, which requires him to kill Curtis Manning who is bent on revenge for an earlier incident. Having found out that Fayed is planning to detonate five suitcase nuclear bombs, CTU agents attempt to retrieve one of them but they are too late. While crying over the loss of his friend Curtis, Jack watches in horror as a nuclear blast destroys Valencia.
