Lupin III: Operation Return the Treasure

In a daring heist at a Moscow casino, Lupin III outsmarts Zenigata, setting off a new adventure that leads him to the estate of the late Mark Williams, a notorious thief who held the elusive Trick Diamond. Accompanied by his faithful partner Jigen, Lupin discovers that their quest for the diamond is complicated by a surprising twist: Mark's dying wish demands that all the treasures he acquired must be returned to their original owners before the diamond's location can be revealed.

As Lupin embarks on this unexpected mission, he encounters the cunning Fujiko, who aids him in navigating the challenges ahead. However, the task is fraught with difficulties, as both Zenigata and a gang led by the casino's ruthless owner are hot on their trail. With time running out and obstacles at every turn, Lupin must outwit his pursuers to uncover the true treasure hidden within Gaudí's iconic Sagrada Familia.
