Chyna Shepherd is a twenty-six-year-old psychology student who survived an extremely troubled past. While visiting Laura Templeton's house, a farm in the Napa Valley, a serial killer named Edgler Foreman Vess breaks into the house, taking Laura and killing her parents. Chyna survives and manages to follow him. In doing so, she learns of Vess's captive: a young, innocent girl, Ariel, trapped in Vess's home far from the Napa Valley. Chyna feels a great sense of responsibility for this girl, and she travels deeper into her nightmare.
