Family counselor Elizabeth Conner isn't sure what to think when Maria Santiago comes to her for help. Pregnant and terrified, Maria claims to be visited each night by the ghost of a little girl, warning her to flee. Her husband, Miguel, a migrant worker at Harcourt Farms in the San Joaquin Valley, dismisses her fears as hormonal changes. Sympathetic to the young woman, Elizabeth agrees to help by contacting Miguel's employers, who own the cottage where the young couple lives.

Elizabeth immediately picks up on the deep enmity between the two Harcourt brothers: Carson, the handsome scion running the estate for his incapacitated father, and Zack, the rebellious black sheep. While Carson is more interested in Elizabeth than in her concerns, Zack grudgingly agrees to help her look into the history of the house.

But even as unexpected desire draws them together, Elizabeth and Zack feel something dark and disturbing at the house. And when the cloying scent and lingering chill of pure evil surround her, Elizabeth knows something terrible has happened here before, something that has its roots in murder....
