When the Democratic presidential candidate is shot and wounded while giving a speech only days before the election, everyone is baffled; there’s no nearby location from which the shot could have come. With the FBI and the Secret Service desperate for leads, they call partially retired Agent Kane Logan to the scene. Using his skills as a sniper, he determines the shot originated from atop the Brooklyn Bridge – almost three miles away. Although the shot borders on the impossible, Kane sets out to run down this theory.

He is ordered to partner with Agent Lilly Alexander, a young wunderkind blessed with an almost superhuman photographic memory. At first, Kane resents her presence, but as they pursue leads and enter the worlds of paramilitary gun extremists, drug-induced brainwashing, and political machinations, he grudgingly admits her amazing ability to connect disparate facts – along with her innate talent to read and play people to her advantage – is invaluable to the investigation.

As they make headway, they grow confused by what the evidence suggests, but as the election gets closer, they become even more relentless in their pursuit of the perpetrators, until even their own agency is trying to arrest them. Who are their enemies? Who are their allies? Can they solve this crime in time to ensure the integrity of the upcoming election and avoid the end of American democracy through a possible coup d’etat?
