Once a blue-collar town, Peacefield is now a place in transition. Luxury town-homes and upscale boutiques have replaced factories and corner stores. One night, the otherwise bucolic town explodes with gunfire. A hostage crisis ensues, and the local police department is caught flat-footed. Officers Grant Ambler and Arnold Strauss are both new to the department, and both carrying the weight of their own personal problems as they walk, unaware, into the mayhem. In a single evening, Peacefield is transformed from a quiet, anonymous place into a violent and unpredictable nightmare, where lives are shattered, faith is renewed and long-concealed mysteries are solved.
