In 1963, FBI Special Agent Tom Warren is transferred to the San Francisco Bureau to lead the effort to break down a well-organized Chinese spy network. Soon after his arrival, he is discreetly given a picture of a murdered Japanese woman with a chopstick jammed into her mouth. Tom recognizes this as the handiwork of his old nemesis, Dr. Wang--the leader of the same Chinese spy network. His last run-in with Dr. Wang resulted in the death of Tom's entire team, and he is determined to have different results when they next meet.
With nuclear secrets on the line, Tom and his new team race against time to find the source of a leak within the United States espionage establishment. As more people on both sides are killed, Dr. Wang becomes even more ruthless while gaining power inside China. No matter what it takes, Tom is hell-bent on bringing down Dr. Wang, if he can crack the tight spy network that keeps him one step behind. Tom has one last but very risky chance to take him down.
Who should he trust?
