Lupin walks into a trap that's actually three traps stacked inside each other, and he knows it the whole time. The ring is never the score, it's the map to the real score, which is never the real score either, and by the time you realize the brooch might actually be a weapon, you've already lost track of who's hunting whom. This is Lupin at his most purely functional: every scene is a setup, every setup is a con, every con is setting up the next con, and the joke is that everyone involved, including you, sees it coming and walks straight into it anyway.

Lupin pulls off a heist at a New York auction, making off with an unassuming ring. Zenigata is soon on his tail, but he is not the only one giving chase. A brutish former KGB agent named Nabikov is after the ring too, working for Cynthia, the ruthless woman who runs the Bank of the World. Cynthia knows the ring points the way to a legendary brooch. Conquerors of the past are said to have drawn special power from it to leave their mark on history. Cynthia intends to use it to spark a bloody international war. With Jigen, Fujiko and Goemon at his side, Lupin races to solve a riddle written in an ancient Mayan language and reach the brooch before she does, in an adventure comedy special where the fate of the world is at stake.
