Christine Morris is awakened early on a chill November morning by a phone call from one of her colleagues, forensic psychiatrist Dr. Leo Forgach. His daughter, Deidre, is missing. Despite the fact that she and the doctor have never seen eye to eye, Christine agrees to help in the search for Deidre -- only to discover her brutally strangled body in a lake.
Heartbroken, Leo tells Christine that his daughter was deaf and has a child she had deliberately ensured would be deaf. As a militant supporter of the Deaf Culture, Deidre wanted a deaf child to make a politcal statement. Although some people supported her stand, many did not -- including Deidre's own father. Christine must use her new skills as a forensic profiler to discover the killer.
