Lupin III: Alcatraz Connection

Inspector Zenigata boards the floating casino Machine Gun Kelly knowing Lupin III intends to empty its vault. Lupin, Jigen, Goemon, and Fujiko do break in, but the money is only part of what interests them. Hidden aboard the ship is information pointing toward a sunken vessel loaded with gold near Alcatraz.

The stolen data draws Lupin into a much larger puzzle involving the San Francisco mafia, a secret organization operating beneath the infamous prison island, and buried history that powerful people would rather keep underwater. With Zenigata closing in from one side and armed enemies from the other, the treasure hunt becomes a race to expose the truth before someone else silences it.
