The aging detective Mikawa Hanshichi is treated as a nuisance at the downtown police station where he is assigned, but to Zenigata he is a great and respected elder. At this time, in celebration of the founding of Asakusa Temple, a golden statuette of Kannon, long since hidden away, will go on display, and Lupin, setting his sights on it, sends word of his intended coming. Hanshichi, who experienced trouble with Lupin ten years before, is determined that this time for sure he will match wits, with a great arrest taking place on the roof of Asakusa Temple. It's official business!
