Dr. Qin Ming, a medical examiner in Longfan City, is calm and sharp-tongued, using his scalpel to cut through to the truth. Police Captain Lin Tao is decisive in action, while assistant Li Dabao possesses an extraordinary sense of smell. The three form an "Iron Triangle," starting from the gutter oil case and proceeding to crack a series of mysterious and suspenseful crimes. They use cold blades to decode the secrets of death, forging an irreplaceable bond through the trials of life and death. When a mastermind targets Qin Ming, the trio resolves long-standing injustices while fulfilling their ultimate commitment to justice—Ghostly hands, Buddha's heart; speaking for the deceased.
"A scalpel is the medical examiner's eleventh finger—the sharpest finger, and the finger that criminals fear most."
