Nora Carleton is back working as a federal prosecutor in New York, but her city is in turmoil. Extremism is on the rise, funded from the shadows and growing in momentum online, with one person in particular fanning the flames. Radio and podcast host Samuel Buchanan uses his platform to spread disinformation and incite violence and his mission is succeeding, with disturbances, clashes, and hate crimes rising across the country. As the threat of a major attack grows, and a United Nations rally is targeted, it seems Nora is the only one who can stop the spread. She must successfully convince a jury that some speech should be treated as a crime, or see her country torn apart.
