七濑美雪（山口春奈 饰演）是被提拔为担任突然失踪的著名模特儿的替角，参加在香港举办的时装秀。青梅竹马的金田一一（山田凉介 饰演）和学弟佐木龙二（有冈大贵 饰演）也一起来到香港。金田一平常看起来对什么事都不在乎，却是名侦探金田一耕助的孙子。正当三人在香港观光时，美雪却突然失踪。美雪绑架没过多久，金田一和佐木偶遇与美雪长得一模一样的女孩，其实她就是突然失踪的著名模特儿杨兰。原来美雪是被误认为杨兰而被绑架，因为在杨兰身上有标示九龙财宝所藏处的刺青，所以想要宝藏的人有可能因此绑架了美雪…其九龙财宝就是20年前香港的九龙城被称为东洋的魔窟时期，价值数十亿的99克拉钻石，而守护财宝的正是称之为“九龙皇帝”的王龙（曾志伟 饰演）。

这部电视剧，由《金田一少年之事件簿》漫画原作者天树征丸先生首次为本系列的剧本亲自执笔。以香港为舞台，外景皆在香港拍摄，一开场就以华丽动作场面展开，是《金田一少年之事件簿》系列史上规模最大的电视剧。此次第四代金田一一由山田凉介（Hey！Say！JUMP成员）担任。台湾演员代表由原台湾超级偶像团体飞轮海成员，在日本以及亚洲各地拥有众多粉丝的汶莱出身吴尊出演。韩国代表由全世界知名的实力派偶像团体BIGBANG最年少成员V.I演出。这部电视剧可以说是目前代表亚洲的顶级偶像们齐聚一堂。另外暌违11年之久出演日本电视剧的徐若瑄以及香港著名演员曾志伟等超豪华演员阵容参加。

日本电视剧举社制作的全球性企划，将为亚洲娱乐圈掀起一股新嘲讽，敬请期待。
