A British weapons expert, codename Chuff, learns that British sophisticated surface-to-air missile have been stolen in the Ukraine, and are now on their way to the US, in a plot to shoot down Marine One over Washington - to assassinate the President.
Hot on their trail, Chuff goes undercover in a far-right training camp in Florida, her actions guided by an octogenarian US intelligence official who has manufactured the plot as a pretext to launch a crackdown against extremist militias who threaten to bring down America.
