When a house explodes with a mother and two children inside, Stan Kobe is called to the horrific crime scene. The father, a former Air Force bomb technician, becomes the key suspect, but disappears and is never found. Ten years will pass before another triple homicide occurs with similarities the savvy prosecutor, Kobe, believes are common to his decade-old cold case.

Convinced the multiple homicides are related, Stan begins an entangled journey to prove his shaky theory to fellow law enforcement as he attempts to solve both crimes. While doing so, though, he discovers more than he bargains for and uncovers what he believes is a domestic terrorism plot targeted to strike his city’s delicate infrastructure. More disturbing is that he may be a target in the crosshairs.

As the terrorists begin their countdown to destruction, planting bombs poised to attack the fragile sustainability of one of the country’s largest metropolitan areas, Stan Kobe embarks upon a frantic race to render safe the situation and save his beloved city, but maybe most importantly those he loves.
