Forensic pathologist Huo Ling returns to Hong Kong to investigate her sister's murder, disguised as an accident. Teaming up with hard-nosed Major Crimes Inspector Shen Yandong, who trusts only physical evidence, she unravels a string of long-unsolved murders. Huo Ling believes that the dead never lie; all lies come from the living. Inspector Shen Yandong holds fast to one rule: intuition does not belong in a case file. A murder on a rainy night unexpectedly connects two deaths from years ago, both ruled to be "accidents." Twelve years ago, her sister died under mysterious circumstances. Seven years ago, his informant met a quiet end. Both murders were committed by the same hand. Rain can wash away bloodstains, but it cannot wash away buried names.
