As a child, Sacha Baseyev endured an unimaginable horror. Today, he lives and breathes for only one reason --- to kill. And he will kill as many Americans as it takes to accomplish his mission.

But as Scot Harvath searches for the man, he uncovers another actor --- a rogue player hell-bent on forcing America’s hand and drawing it into a confrontation deadlier than anyone could have imagined.
