A disputed horde of recently discovered ancient gold coins draws the attention of Lupin and company. As the ownership of the coins is disputed, Lupin decides to settle the matter on his own by stealing them from the Dai Nippon Bank. This time, Zenigata decides not to wait for Lupin to carry out the hit but to counterattack by locating and raiding his hideout. After a dispute with his chief, he also offers him a letter of resignation in case of a further failure, and vows to stop Lupin on his own in one final showdown.
