The blind spot of silence happens to be the suture for the murderer to stitch up the truth - a detective who is afraid of wrongly accusing good people due to a miscarriage of justice in an old case must hunt down a man who uses "treatment" to disguise murder and sews all wounds with his left hand after the belief that "it is impossible for a mother to kill her daughter" collapses.
Motto: "Evidence doesn't lie, but people who believe it do."
