Ex Philadelphia Police Sergeant, Brant Discher, now a small-town cop, doubts the validity of a local 'suicide case'. He suspects the self-inflicted death of a young, Middle Eastern man has been staged to look like something it is not. Compelled to go rogue, he uncovers the makings of a masterfully complex and sinister plot. With every turn, it seems to go deeper than even he could imagine.

They are unaware of the breadth of their assignment, or each other. Unknowingly, all will participate in a national mass attack coordinated for a specific date, etched in stone for over a decade.
