At five thirty am, on a cold April morning, a suburban commuter stumbles over a body in an empty stretch of land used as a parking lot in one of Chicago's small suburbs, Park Ridge. The murder victim, Michael McGivney, is a young lawyer, a commuter on his way to work. The money and personal effects are still on the victim. Robbery does not appear to be a motive. The hole in the victim's chest is perfectly round and cauterized. It’s also huge enough to stick one's fist clear through it. When the forensics report that the victim's face is heavily tattooed with bizarre tracks suggesting road-works infrastructure, the CPD detectives, Carly and Bill know this case is not going to be closed quickly…if at all.
