US Customs officer Alex Brooks uncovers the plot of Russian arms dealers who planned to smuggle nerve gas into the U.S. In order to avoid publicity, the boss of the small customs station in Alaska decides that the dangerous barrels should be sent to a safe compound by train. Meanwhile, the Russian terrorist responsible for the smuggling, Simeonov, is being delivered via plane to Washington until a group of his henchmen rescue him. Brooks and the Russian agent Natalya are the only people capable of stopping Simeonov and his group of terrorists from keeping control of the train carrying the deadly nerve gas.
