In the doldrums of a broiling Washington summer, a madman goes on a shooting rampage in the Capitol building. Sully Carter is at the scene and witnesses the carnage firsthand and files the first and most detailed account of the massacre. The shooter, Terry Waters, is still on the loose and becomes obsessed with Sully, luring the reporter out into the streets of DC during the manhunt. Not much is known about Waters when he is finally caught, except that he hails from the Indian reservations of Oklahoma. His rants in the courtroom quickly earn him a stay at Saint Elizabeth’s mental hospital, and the paper sends Sully out west to find out what has led a man to such a horrific act of violence.
As Sully hits the road to see what he can dig up on Waters back in Oklahoma, he leaves his friend Alexis to watch over his nephew, Josh, who is visiting DC for the summer. Traversing central Oklahoma, Sully discovers that a shadow lurks behind the Waters family history and that the ghosts of the past have pursued the shooter for far longer than Sully could have known. When a local sheriff reveals the Waters’ deep connection with Saint Elizabeth’s, Sully realizes he must find a way to gain access to the asylum, no matter the consequences.
