Special Agent Jeb Foster and the Rapid Intervention Team he leads are recruited to help the Russians retrieve 500 tons of stolen weapons-grade nuclear material. Although the United States and other countries were assisting the Russians to secure these stockpiles, many were known to be vulnerable. When Jeb learns that not one, but multiple thefts have taken place from supposedly secure locations, he and the team go to secret cities where few outsiders have ever set foot. Sabotage leaves him stranded in the Arctic wilderness, and as time is running short, Jeb fears the thieves will escape Russia with the stolen nuclear material. The body count of those who could have provided valuable information steadily mounts, making his task all the more difficult. He knows that if the stolen material passes into the hands of the terrorists, who likely contracted for its theft, it will be for the sole purpose of delivering a devastating blow to several major American cities.
