Greedy Russian military officers crash two trains into each other with the warheads aboard one causing a nuclear blast. The accident is a cover for the theft of some of the weapons for sale to terrorists and rogue governments. In the U.S., intelligence officer Lt. Col. Tom Devoe, isn't fooled. Neither is Dr. Julia Kelly, the acting head of a White House task force on nuclear smuggling. Devoe and Kelly team up to find the nukes, but one warhead is missing. It's in the hands of Dusan Gavrich, a grief-stricken terrorist planning to call the world's attention to the war in Croatia with a nuclear explosion in Manhattan.
