Lupin III joyrides through
Tokyo. Happening upon a
prisoner transport van escorting beautiful thief
Fujiko Mine to prison, a smitten Lupin resolves to help her escape and win her heart. Though he breaks her out of prison that night, Fujiko knocks him unconscious and flees. Lupin is arrested and interrogated by
Inspector Zenigata but, with no evidence linking Lupin to the jailbreak, Zenigata must release him. Lupin's grandfather was
Arsène Lupin, a
French gentleman thief. Arsène's son, Lupin II, expanded the criminal enterprise to the worldwide "Lupin Empire", an organization with tens of thousands of recruits; he was eventually betrayed and his organization was crushed by the rival Maccherone crime family.
Marksman Daisuke Jigen, the sole survivor of this massacre, has since searched for any surviving members of the Lupin family who could revive the crime empire. Though Jigen is able to ally himself with Lupin III, he is disappointed to discover the young man prefers to live freely as a criminal
vagabond and shows no interest in rebuilding the Lupin Empire. Inspector Zenigata, accompanied by detectives Ooka (descendant of
Ōoka Tadasuke) and Toyama (descendant of
Tōyama Kagemoto), is assigned to investigate Lupin as the police department lacks any evidence with which to press charges. Though they come face-to-face with Lupin and Jigen at a scrap yard, the criminals are able to escape with ease while Zenigata suffers injuries from the chase. Later, at Fujiko's behest, Lupin attempts to steal 560 billion yen's worth of jewelry from an exhibition. A squad of policemen, led by Zenigata, are waiting in the exhibit's vault and give chase. Though Lupin and Jigen escape, they lose track of the jewels in the confusion; Fujiko, having eluded the police, takes them for herself. The head of the Maccherone crime family, having learned that a descendant of Lupin is alive and active in Japan, is concerned that a revived Lupin Empire may again threaten their organization. He commands the organization to kill Jigen and Lupin, and
hitmen are dispatched. Lupin is able to defeat the assassins – a
cowboy, a
sniper duo, and a sextet of dancers disguised as
nuns – but decides to surrender himself to Zenigata for protection. Assuming that the captive Lupin will soon be executed, the Maccherone boss turns his focus to a new mission: stealing a
dogū figurine thought to contain
psychokinetic energy, to be auctioned off on the
black market. Fujiko, spying on the meeting and hoping to take the figure for herself, is discovered and captured. Though Lupin had been content to stay in prison, the news of Fujiko's capture spurs him into action and he breaks out to save her. Zenigata is taken off the Lupin case and reassigned to transport the psychokinetic figure to a national research facility. Maccherone thugs ambush the police convoy on a mountain trail. Jigen, piloting a helicopter, takes advantage of the confusion to steal away the statue; meanwhile, Lupin moves to rescue Fujiko from her nearby confinement. Though Jigen retrieves Lupin and the freed Fujiko, a puncture in his helicopter's gasoline tank forces him to make an emergency landing. Ironically, the trio lands at the research facility: they have accidentally delivered the statue to its intended destination. The police chief prepares an official certificate of thanks for Lupin for his efforts in saving a national treasure, and a frustrated Zenigata is assigned to hand-deliver the award. Lupin, Fujiko, and Jigen relax by the city docks, with Jigen reflecting that the reformation of the Lupin Empire is unlikely. When Zenigata arrives, the group mistakenly believes he is there to arrest them and a madcap chase ensues. == Cast ==
