Follow Special Crimes Unit Detective Beck McManus and his hunt for the Doll Collector. Six little girls—each about to turn seven years old—go missing in broad daylight without a trace. McManus and his long-time partner, Evan Graves, are tapped to head the investigation despite virulent protests from the police commissioner, who cites McManus' own daughter's kidnapping three years prior as evidence of his unsuitability. That case was never solved, and his daughter's disappearance nearly cost Beck his career—and his sanity.
