As a new authoritarian movement rises in American politics, stoked by one of the country’s most outrageous demagogues, there is an all-out international manhunt for an American traitor. The U.S. Army’s Nazi war crimes trials in Germany have been infiltrated by a spy -- a mole for the other side. A gruesome foreign influence operation unfolds in Washington. A blackmail plot turns deadly in the U.S. Senate. A Hail Mary scheme to stop the counting of the Electoral College votes rattles democracy’s cage. With the line between the violent ultra-right and mainstream American politics fraying beyond recognition, with the FBI always one step behind their quarry, Americans of all stripes step up to confront a seemingly unstoppable, ascendant, anti-democratic force.
