Keri Locke, Missing Persons Detective in the Homicide division of the LAPD, remains haunted by the abduction of her own daughter, years before, never found. Still obsessed with finding her, Keri buries her grief the only way she knows how: by throwing herself into the cases of missing persons in Los Angeles.

A routine phone call from a worried mother of a high-schooler, only two hours missing, should be ignored. Yet something about the mother’s voice strikes a chord, and Keri decides to investigate.
