As Reiko delves into the murder of a real estate mogul, she uncovers a smudged dying message, a bloodied trophy, and a curtain cord that’s been violently pulled. Despite her efforts, she finds herself at an impasse—until the brutal butler Kageyama steps in with a solution. Together, Reiko and Kyoichiro employ unconventional tactics to ensnare the killer, gaining insight into the victim's psyche and putting a stop to a cycle of vengeance that has spiraled out of control.
