After a bomb explodes an SUV in New York City that might be carrying a BAU member, the team goes into high gear to determine who might have been injured in the explosion and to apprehend the terrorists responsible for the mayhem.

20 months after last season's shocking season finale, when Jack Bauer was captured by Chinese government agents and taken battered and bloodied to points unknown, a series of horrific terrorist attacks rocks the nation. President Wayne Palmer, the strong-minded brother of the late President David Palmer, and his team of advisors, including Karen Hayes, Thomas Lennox and CTU colleagues Chloe O'Brian, Curtis Manning and Bill Buchanan, begin an unthinkable, nail-biting day.

Commander Harmon “Harm” Rabb, Jr. and Lt. Colonel Sarah “Mac” Mackenzie are sent to find out exactly what went wrong during NATO Transit exercises where seven men died in a collision.

Wayne prepares to talk to the nation as L.A. deals with the fall-out from the nuclear blast. Fayed tries to set up a deal with a new trigger man who can help with the four remaining bombs. Sandra is outraged when the FBI forces Walid to wear a wire in the hopes of gaining information from his fellow inmates. Assad provides CTU with a lead, but Jack finds that it takes a personal twist when he learns that the terrorists may have connections to his estranged family.

Jack tries to locate Assad in hopes of warning him about the impending air strike. Assad agrees to help Jack locate Fayed, but Jack worries that he’s forgotten how to do his job. Ahmed finds he must take drastic action when his role in the attacks is discovered. President Palmer’s sister, Sandra, goes a long way to defend her principles when she finds herself and her civil rights organization to be a target in an FBI investigation.
