A brilliant madman dedicated to anarchy has dark plans for the U.S. In twenty-four hours, America will be plunged into chaos—the result of an unthinkable assassination to be carried out flawlessly—and the government has no inkling of the catastrophe that is about to occur.

Only one man can prevent the nightmare: disgraced rogue CTU operative Jack Bauer. But Bauer's been cut loose, is wanted for murder, and is running from the police, who have orders to shoot to kill. And there's no one he can turn to for help—because a high-level traitor in CTU wants Jack Bauer dead.
