A serial killer has the city of Boston in his grip. He's killing with antique Revolutionary War weapons and leaving bodies at markers on the city's historical Freedom Trail. No one is safe—especially those with ancestry ties back to the Patriots.

FBI Special Agents Kate Walsh and Declan James rush to the aid of local authorities to help catch a killer in their hometown. As a descendant of one of the signers of the Declaration of Independence, Agent Walsh is in the killer's crosshairs. Part madman and part mastermind—no one knows who is next.

With potential ties to an underground subversive group known as The Founders, can the FBI stop a killer whose wake of destruction has only just begun or will the city become paralyzed by this killer's centuries-old political agenda?
