Lupin the IIIrd the Movie: The Immortal Bloodline

Lupin III and his friends are on a mission to uncover the identity of a mastermind who's been sending assassins to a mysterious island in the Bermuda Sea. Their goal is also to find a vast treasure supposedly hidden on the island. However, their plane is shot down by snipers, and they crash-land on a desolate island filled with decaying weapons, nuclear missiles, and mutated "garbage men" created as weapons. The island is shrouded in a deadly fog that can kill within 24 hours, making escape nearly impossible.
