Arsene Lupin III discovers that the spoils from his latest casino robbery are actually Gothic Bills, legendary counterfeits that are nigh impossible to distinguish from genuine bills. Together with colleague Daisuke Jigen, he heads to the small nation of Cagliostro to investigate the origin of these counterfeits. Upon arrival, they save a girl from a high-speed chase who turns out to be Clarisse d' Cagliostro, the daughter of the late Duke d' Cagliostro. She is running from a sinister plot by Count Cagliostro to steal her family's treasure through a forced marriage. Natural flirt Lupin dislikes seeing a girl in distress and seeks to remedy the situation. Goemon Ishikawa XIII, Fujiko Mine, and Kouichi Zenigata also join the fray, each with their own motivations. As everyone converges at Cagliostro Castle, Lupin reminisces about his visit there 10 years ago, and the castle's secrets emerge from the depths.

Arsène Lupin III is the grandson of world-famous thief Arsène Lupin, and he's living up to his grandfather's memory as a high-profile thief himself. Due to his infamy, Lupin III attracts the attention of the persistent Inspector Zenigata of the ICPO, as well as rival criminals. Lupin III's criminal lifestyle even seeps into his love life. The main woman in Lupin III's world is femme fatale Fujiko Mine, who Lupin III can never tell is working with or against him. Follow Lupin and his gunman partner Daisuke Jigen on their quest to own the world－or at least the valuable bits!
