In this high-octane thriller, a laboratory scientist races to stop terrorists from detonating a nuclear bomb on American soil. Tasked by the FBI to analyze a small amount of highly enriched uranium found on a smuggler in Moldova, nuclear-forensics scientist Steven Carter’s initial results suggest a serious terrorist threat. Unconvinced by his findings, the FBI calls a halt to further investigation. But Carter goes rogue, secretly continuing to analyze the material and discovering compelling evidence that somebody has enough uranium to make a nuclear bomb. With no other recourse, Carter risks his career by taking his evidence to the CIA. Later, when a piece of the weapon is interdicted, he reunites with his FBI handler, John Kittrick, to decipher the clues buried in the uranium. With time running out, against all protocol, Kittrick asks Carter to leave his safe scientific turf and enter the dangerous world of a field operative. And Carter agrees, willing to do anything to help find the bomb before the terrorists unleash nuclear destruction.
