After becoming pregnant, Nora is brutally murdered by a killer in black, who cuts out her unborn child, severs her body, and dumps her in the slums. Her lingering spirit remains trapped on Earth, watching her detective husband, Dorian, work the case. Distant from his wife and blinded by trust in his first love, Iris, Dorian refuses to believe the victim could ever be Nora. While tracking down remnants of the Black Dahlia gang, he repeatedly overlooks vital clues, including medical records, a preserved fetus, and a missing persons report. As DNA testing proceeds, he is forced to face the horrifying truth: the wife whose final cry for help he hung up on, and whom he accused of lying, is the mutilated body on his autopsy table, while the real murderer, Iris, still lurks right by his side, biding her time.
