Lupin swipes a ring from a New York auction, and Zenigata is hot on his trail... along with a gun-toting, former-KGB brute named Nabikov. Nabikov's boss is Cynthia, the lady in charge of the BOW: Bank of the World. Cynthia knows the ring is actually a guide to the location of a fantastic brooch once worn by conquerors of years past. The brooch, it is said, gave them special powers to become more than mere men and women, and make their marks on history. Can Lupin and his cohorts find the brooch before Cynthia uses it to make her own mark with bloody, international war?
