His daughter, Deirdre, is missing. Despite the fact that she and the doctor have never seen eye to eye, Christine agrees to help him search for Deirdre—only to discover her brutally strangled body in the lake. Heartbroken, Leo tells Christine that his daughter was deaf and had recently given birth to a child she had deliberately ensured would be deaf.

Christine must use her new kills as a forensic profiler to discover the killer.
