In southern Texas, on Saturday nights, women are disappearing. One vanishes from a movie theater. Another is ripped from her car at a stoplight. Another vanishes from her home while checking on her baby. Rookie FBI agent Caitlin Hendrix, newly assigned to the FBI's elite Behavioral Analysis Unit, fears that a serial killer is roaming the dark roads outside Austin. Caitlin and the FBI's serial crime unit discover the first victim's body in the woods. She's laid out in a bloodstained, white baby-doll nightgown. A second victim in a white nightie lies deeper in the forest's darkness. Both bodies are surrounded by Polaroid photos, stuck in the earth like headstones. Each photo pictures a woman in a white negligee, wrists slashed, suicide-style--posed like Snow White awaiting her prince's kiss.
