On a beautiful Saturday in downtown Saint Paul, Minnesota, state investigator Kirk Stevens and FBI special agent Carla Windermere, witness the assassination of one of the state’s wealthiest men. The shooter is a young man, utterly unremarkable…except for the dead look in his eyes.

But just who has the dead-eyed shooter targeted next…and who’s choosing his victims?
