The terror-alert level has just been raised...Although retired from CTU, Jack Bauer finds himself in the middle of a terrorist plot after the U.S Secretary of Defence and his daughter are kidnapped.

But its soon evident that the kidnapping is part of a much larger plan, for every time Jack thinks he's averted disaster a new and more ominous plot is uncovered.

As CTU races to figure out the terrorists' true objective it becomes clear that the events of this day have been years in the making and only a miracle will disrupt the scheduled attacks that the terrorists hope will bring the country to its knees.
