In the middle of a heated election campaign for the governor's seat of Georgia, the FBI is informed of a planned terrorist attack on Atlanta's new conference center. Only 24 hours remain to find and disarm the bombs, save the NATO summit, and thousands of lives. In a sinister maneuver, the ex-terrorist Shadid is recruited out of prison and teamed up with the conference center's project manager Sarah, a woman whose husband has died in one of his former attacks. But crawling through the building's bowels, Shadid discovers more than a time fuse of perfidious ingenuity.
