Rupan sansei: Kariosutoro no shiro
Master thief Arsène Lupin III and his colleague, Daisuke Jigen, flee the Monte Carlo Casino with huge quantities of stolen money. They escape in Lupin's Fiat 500, but Lupin recognizes the bills as distinctively high-quality counterfeits. Deciding to seek out the source, they head to the Grand Duchy of Cagliostro, the alleged wellspring of the counterfeits.
Shortly after arriving, they rescue a young woman being pursued by a gang of thugs, with her and Lupin falling off a cliff while escaping. Lupin is knocked unconscious, and the woman captured, but she leaves him a signet ring. Lupin recognizes the woman as Clarisse, the princess of Cagliostro, who will soon be married to Count Cagliostro, the country's regent. The Count's arranged marriage will cement his power and recover the fabled ancient treasure of Cagliostro, for which he needs both his and Clarisse's ancestral rings.
A squad of assassins attack Lupin and Jigen at their inn but fail to kill them or recover the ring. Lupin leaves his calling card on the back of Jodo, the Count's butler and chief assassin, announcing he is going to steal Clarisse. Lupin summons Goemon Ishikawa XIII to aid their quest to rescue the princess and tips off his longtime pursuer, Inspector Koichi Zenigata, to his whereabouts to provide a distraction. Zenigata's presence and a party give Lupin enough time to sneak into the castle. There he finds his on-off lover, Fujiko Mine, posing as Clarisse's lady-in-waiting, who tells him where the princess is being held. Lupin makes his way to Clarisse and returns her ring, vowing to help her to escape. Before he can act, the Count drops Lupin down a trapdoor into the castle's catacombs, as Lupin had planned. Lupin mocks the Count through the ring he gave to Clarisse – a fake containing a transmitter – and the Count sends three assassins to retrieve the real ring.
Lupin encounters Zenigata, who was accidentally dropped down earlier, and they form a pact to help each other escape. After overpowering the assassins, they escape into a room full of printing presses — the source of the counterfeits. Zenigata wants to collect evidence, but Lupin points out they must escape the castle first. They start a fire as a distraction and steal the Count's autogyro. However, as they attempt to rescue Clarisse, Lupin is shot. Clarisse offers the ring to the Count in exchange for Lupin's life. After securing the ring, the Count's attempt at betrayal is foiled when Fujiko's actions allow her, Lupin, and Zenigata to flee. As Lupin recovers from his injuries, Zenigata attempts to convince his superiors at Interpol to prosecute the Count for counterfeiting, but fearing political repercussions, they halt the investigation and remove him from the case. Meanwhile, Lupin intends to stop the wedding and rescue the princess. He also reveals his reasons for rescuing Clarisse to Jigen, Goemon and her former groundskeeper — as a young girl, she had saved his life during his unsuccessful first attempt to find the source of the counterfeit bills ten years earlier. Fujiko tips off Lupin on a way to sneak into the castle, and forms a plan with Zenigata to publicly reveal the counterfeiting operation under the cover of pursuing Lupin.
The wedding appears to go as planned with a drugged Clarisse until Lupin's "ghost" disrupts the ceremony, and despite the Count's precautions Lupin makes off with both Clarisse and the Count's rings. Meanwhile, Zenigata and his squadron arrive in the chaos and the inspector leads Fujiko, posing as a television reporter, to the Count's counterfeiting facility to expose the operation to the world. The Count pursues Lupin and Clarisse to the face of the castle's clock tower. Lupin is forced to surrender the rings to save Clarisse, and they are both knocked into the lake surrounding the tower. After using the rings to reveal the secret of Cagliostro, the Count is killed by the mechanism unveiling the treasure. Lupin and Clarisse watch as the lake around the castle drains to reveal exquisite ancient Roman ruins — the true treasure of Cagliostro. Lupin and his friends bid farewell to Clarisse, now the rightful ruler of Cagliostro. With Zenigata pursuing them again (for the crime of "stealing Clarisse's heart") and Fujiko fleeing with the plates from counterfeit printing presses, Lupin and the gang drive out of Cagliostro, with the police close behind them.
