Based on the best selling novel by Patricia Cornwell. Andie MacDowell returns as DA Monique Lamont for another tense crime drama. Lamont and investigator Win Garano reunite to investigate Boston's most famous criminal. Attempting to generate much-needed publicity for her flagging political aspirations, Lamont orders Garano to reopen the investigation of the brutal, decades-old murder of a young blind woman named Janie Brolin. Janie's boyfriend was the main suspect in the original investigation, but Lamont has another suspect in mind - the Boston Strangler. Garano must work closely with a no-nonsense and combative female detective named Stump (Ashley Williams) to unpeel layer upon layer of the 40-year-old crime. Garano and Stump's relationship evolves as they uncover the truth about Janie's death and track down a psychopath who is leaving their witnesses and colleagues dead in his wake.
