平日里游手好闲看似极不靠谱的私立不动高中二年级生金田一(堂本刚 饰)却是个智商很高的推理天才,他和青梅竹马的美女七濑美雪(友坂理惠 饰)、警部剑持勇(古尾谷雅人 饰)等伙伴和朋友,携手解决了不少棘手事件。且金田一解决事件的方法比较特别,他依赖于货真价实的证据,再依照证据来思索和推理,由此及彼,再由彼及此,这样循环往复,最终推理出犯罪凶手。而对于凶手,金田一并不是要把凶手逼向绝境,而是给予其舍生处地的想法,最后加以规劝,使凶手最后以自首结束。借由金田一我们一起进入不思议的案件当中。 本剧改编自同名漫画,是系列作的第二部。
Chatfah, the youngest sister of the Bupphachinda family, has just received the largest share of her father's inheritance and is about to be married. However, Chatfah falls from the highest floor of a vacation home to her three older sisters' shocked eyes. When her body disappears, her three sisters—Baibua, Chomphu, and Picha—become suspects in her disappearance. The eldest sister Baibua is composed, wise, and has always sacrificed for her family. The second, Chomphu, is a confident model whose boyfriend Chatfah stole and was engaged to. The third, Putpichaya, is a jewellery designer and the closest to Chatfah. The three search for Chatfah while further tragedy befalls them following their youngest sister's disappearance. When no one else can be trusted, the three sisters must try to trust one another. They move back to their childhood mansion to find out who was behind Chatfah's disappearance, which could very well be one of them.
