The first time Darby almost died was on the night of her sixteenth birthday. Out with her two best friends, she witnessed a horrible scene - a woman who was tortured and beaten and left for dead in the woods. After being chased by the criminal, Darby looked to her constant savior - her father, "Big Red," a local police officer, and her hero. As always, he made Darby feel safe by promising to find who did this and bring him to justice.

Years later, Darby is now also a cop, having designed her career after her late father's. She is investigating a serial killer who has already slaughtered several young women. There is something eerie about this case from the beginning, and Darby is dismayed when she learns that two of the victims are her childhood friends - the same girls she was with the night she saw the woman in the woods. Soon, it becomes clear that this is no coincidence. Darby is targeted as the next victim, and this time Big Red is not around to save her. Instead, Darby delves further into the investigation, and quickly discovers evidence linking her father to the killer. With no one to save her and not knowing who to trust, Darby struggles to preserve her father's memory as she fights to defend herself against a ruthless killer - one with an unknown motive and a clear plan for murder.
