For the first time in New York City, Jack Bauer is reluctantly drawn into action as President Allison Taylor negotiates plans for international security with Middle Eastern leader Omar Hassan. As the 8th day keeps unfolding, we learn that CTU, now upgraded and operated by M.B.A.-schooled Brian Hastings, still has Chloe O'Brian, but also expert analyst Dana Walsh and systems analyst Arlo Glass.

With only seven hours left in the series' final harrowing day, Jack Bauer sets out to avenge the tragic life-changing events that he has endured. As things become even more personal for Jack, he heads to CTU for an intense meeting after learning of a devastating development. Meanwhile, on the verge of achieving peace on a scale that has eluded the world for generations, President Taylor becomes deeply conflicted when former President Logan sits down at the bargaining table.
