When two boys find a car at the bottom of Sturgeon lake, two local college students drowned inside, the town of Pocono, Pennsylvania is shocked. When a mother and her young daughter find four college students dead at the local orchard a month later, the town starts to question if the events are somehow related. A month later, when six college students are hunted down during an annual party, the town panics. With the possibility of a serial killer on the loose, the town and college go on lock down. The police force has very little to work with--the deaths seem connected but not enough to help put an end to the case.
With the citizens outraged at what they see as incompetence on the part of the police department, the police chief requests help from Lindsey Scott, the best criminal profiler in the country. Putting the clues together, Lindsey is able to get inside the head of the killer. Calling himself the 'Man in the Moon', the killer is just as mysterious as the symbol. The pressure mounts when another eight students are murdered--bringing the total to twenty students in just four months. Lindsey must use all of the clues, her skills as a crime solver, and help from a professor at the university to demystify the Man in the Moon and prevent him from killing again.
Lindsey Scott, the best profiler in the country, takes six months vacation from her stressful and grueling job in order to reconnect with her children. As she begins her first vacation in years, she realizes she's facing her scariest case yet—the task of raising her teenagers, something she avoided up to this point.
When brutal murders begin happening across the country, and no one can figure out who's responsible, Lindsey has no choice but to return to work. With the clues in front of her, Lindsey realizes that while there's one trademark—a blood red eye—left at every murder scene, there's actually more than one murderer involved. But what is motivating the killers to work together? And how are they picking their victims?
Pressure adds as bodies continue to turn up on practically a daily basis. Lindsey goes on a cross country hunt to put an end to the killing spree. But catching killers is a difficult task—even more so when you don't know how many there are. And when Lindsey finally gets close to solving the case, one of the killers targets her fifteen year old son. With time running out for her son, Lindsey must race to put the pieces together and find the killers before it's too late.
