Lupin the Third: The Mystery of Mamo

Zenigata travels to Castle Dracula in Transylvania to confirm Lupin's demise. The body he finds is a decoy Lupin uses to fake his death and slip away. Lupin's escape marks the start of a long cat-and-mouse chase.

Following Lupin's trail, Zenigata heads to Egypt, convinced Lupin will strike the Giza Necropolis next. Lupin and his comrades flee toward Egypt with the Philosopher's Stone in their possession. The chase now spans continents as the team pursues their goals.

In Paris, Fujiko Mine betrays Lupin by stealing the Stone for a mysterious client. Lupin discovers the Stone is a fake, designed to trap him and reveal the betrayals around him. The revelation deepens the tension between the crew and Mamo's schemes.

Flinch, Mamo's henchman, destroys Lupin's hideout, scattering the gang. Jigen and Goemon blame Fujiko for the loss, while Lupin tries to calm their fears and vows to abandon his feelings for Fujiko. The group starts to fracture under pressure.

With nowhere else to go, the trio heads toward the ocean and eventually finds a house with food and water. The reprieve is brief, as the looming threat of Mamo's forces remains. The shelter buys them time but not safety.

A wounded Fujiko returns to seek Lupin, forcing him to break his vow to give up his feelings for her. Flinch arrives to procure them for Mamo, driving the group deeper into danger. Jigen and Goemon confront the fallout of Fujiko's actions.

Jigen later discovers Flinch's plane taking off and follows a clue to its destination. Meanwhile, Jigen and Goemon are briefly questioned by American agents about Mamo and are released when they can't answer. They finally decipher Fujiko's clue, which leads them to Mamo's Caribbean island.

On Mamo's Caribbean island, the billionaire explains his immortality scheme and his decades-long cloning technique. He reveals that he has cloned Lupin, testing his skills and loyalty. Lupin realizes the danger is bigger than a single stone and confronts Mamo directly.

USAf forces attack the base as Lupin, Fujiko, and Jigen try to escape. Jigen rescues Lupin and Fujiko, and Lupin seemingly kills Mamo in a climactic shootout. Goemon duels Flinch, but the sword is damaged and he departs to train.

Zenigata confronts the new reality that the Lupin case is bigger than a single chase. The ICPO chief informs him of the wider conspiracy, and Zenigata resigns to chase Lupin as a private citizen. The pursuit expands beyond the police to personal vendetta.

In Colombia, Lupin and friends encounter Mamo again, who confirms his control of history through cloning and his plan to repopulate the Earth. He even admits cloning Lupin, turning an external threat into a personal mockery. The trio realizes the fight is against a being who has existed for ten thousand years.

Inside a temple fortress, Mamo pushes Fujiko toward his Earth-repopulation plan by launching nuclear missiles. Lupin sabotages the scheme by rigging the missiles to explode before launch, and a laser duel ensues with Mamo. Lupin ultimately incinerates Mamo using Goemon's sword tip to deflect lasers.

A rocket lifts off containing a giant brain that reveals itself to be the original Mamo. Lupin realizes that Mamo's power resided in his clones all along, not in a single body. The brain is jettisoned toward the sun as Lupin and Fujiko escape the launch with improvised explosive timing on the rocket.

Lupin and Fujiko survive the rocket scare and attempt to regroup, but Lupin is briefly captured by Zenigata. Fujiko is rescued by Jigen, while Lupin and Zenigata escape on foot with their ankles shackled together. Goemon ends the film with a self-referential, fourth-wall-breaking closing line.
