While attempting to win the affections of a beautiful rival, a master thief risks death to learn the secret intentions of a wealthy and seemingly immortal, but certainly ruthless, recluse.

Master thief Lupin the Third and his friends have to compete with a greedy banker and her minions to help solve a mystery leading to a treasure that is said to hold history's most powerful rulers.

After robbing a Moscow casino right under Zenigata's nose, Lupin is given a job to return 6 treasures to their original areas for an old friend of his, so Lupin can receive an even better treasure to gain.

Notorious thief Lupin the Third aims to steal the lost treasure of the Romanov royal family with his criminal associates along for the ride. The treasure is an immense quantity of gold hidden underground in the vaults of a mysterious Texas bank. But to obtain the gold, Lupin and his friends will have to face down both the Mafia and Rasputon, the telepathic descendant of the mad monk Rasputin. Lupin again eludes inspector Zenigata with the help of a mysterious blonde named Judy Scott, as Rasputon manipulates the world's leaders to put every obstacle in Lupin's path.
