For most cops, nightmares were just another unfortunate aspect of police work and Alex Taylor was no different. After a lifetime in law enforcement, she thought she had seen them all: The cold-hearted perpetrators, the horrific, blood-chilling crimes, the innocent victims. All that was supposed to have changed when she left the mean streets of Brooklyn and moved up to the tranquil, wooded mountains of New Hampshire, but now the unnerving nightly visions, of the one she couldn't save, are pushing her to the brink of a nervous breakdown. As Alex struggles to find some mental relief, she is suddenly thrust into a life or death encounter that quickly spirals out of control. In the aftermath, she finds herself in the unenviable position of being Monday morning quarterbacked by investigators and even begins to wonder if she can truly rely on own memories. As she tries to pick up the pieces, Alex is unaware that the real nightmare has only just begun.
