Then two violent deaths disrupt the core of what they once shared.

Five years later, the friends are drawn back together as new facts about their mutual history are revealed, and what was held to be a tragic accident is discovered to be murder. As the true story emerges, other secrets begin to unravel and the casual cruelties of high school develop into acts of violence that threaten an entire city.
