Nursery owner Austin Ward suffers from a paralyzing fear of darkness, the result of a childhood trauma. Each time her fears drive her to an anxiety attack and a loss of consciousness someone she cares about dies. As the body count rises she is driven to find the killer, but where should her search begin? Is someone seeking revenge? Has a serial killer come to her quiet Pacific Northwest town? Or, has something sinister followed her from childhood—something she met once before—in the dark?
