Unforgivable [Film and TV Commentary]

Recently, a horrific murder occurred in the city. The exposure of a female corpse cut into six pieces and the impunity of the murderer caused panic in society. In exchange for taking a vacation, Investigation Division researcher Jiang Minhao (Xue Jinggu) took on this difficult case. Acting vigorously and resolutely, he teamed up with the reasoning genius Min Ruiying (played by Han Hyejin), and the investigation made rapid progress. The name of the suspect Li Shenghao (played by Ryu Seung-bum) gradually surfaced. Li Shenghao confessed to the crime he committed once he was arrested, but Jiang Minhao discovered that the truth was not as simple as he said. At this juncture, Jiang Minhao's daughter suddenly disappeared, and he knew that this was definitely related to Li Shenghao. Li Shenghao told Jiang Minhao that if he wanted to know the whereabouts of his daughter, he must play a puzzle game with him - solving the puzzle he left on the body. A bet with life as a bargaining chip begins.
