Lupin III: Otakara Henkyaku Daisakusen!!

After stealing from a Moscow casino, Lupin hears that legendary thief Mark Williams has died while hiding the Trick Diamond. Mark leaves behind an infuriating condition: before Lupin can learn where the diamond is, he must return a collection of treasures Mark stole during his lifetime to their rightful places.

Lupin, Jigen, Goemon, and Fujiko race across Europe carrying out a job that runs opposite to their profession, while Inspector Zenigata and a ruthless casino boss pursue them. Each returned treasure brings Lupin closer to the clue hidden in Barcelona's Sagrada Família, where Mark's final prize waits behind a trail designed for another master thief to solve.
