Parker City, 1984... Three years after the Spring Strangler case rocked the historic Western Maryland city nestled at the foot of the beautiful Blue Ridge Mountains, life has returned to normal for Detective Ben Winters and his partner, Tommy Mason. With a new chief now leading the department and the city slowly crawling out of its economic distress, everything seems to be moving in the right direction. Until one sweltering summer day, a killer begins targeting police officers. Ben and Tommy find themselves once again leading an investigation the likes of which Parker City has never seen. The detectives quickly come to realize that until the shooter is found, everyone wearing a badge is in danger. To complicate matters even further, when a recently unearthed skeleton mysteriously connects to the string of police homicides, Ben and Tommy begin to think their current case may be tied to events twenty years earlier. But how could a skeleton buried two decades ago hold the key to solving their current case?
