Lupin III’s not interested, but Jigen stays close to the kid’s side, loyal to the Lupin genetics. To further complicate things, the Maccherone mafia family (pronounced “macaroni”) wants to off Lupin III so that the Lupin mafia stays non-competitive. To further further complicate things, an incompetent cop named Zenigata is determined to arrest Lupin III at any cost, despite the fact that he has no physical evidence that Lupin III has committed any crime. And that’s just the first act - or just about.
What follows is a lot of great pratfalls, bonks on the head, popcorn spit, jokes bashing Lupin III’s sexual orientation (many of which pose Lupin III as the “feminine” type, with police officers acting as his “masculine” counterpart), and very little psychokinesis. In fact, the title Lupin III: Strange Psychokinetic Strategy barely seems to make any sense - just the source of a few jokes where Lupin III brags about his “psychokinetic” powers (which primarily seem to be used for opening safes and doors...and involve his hands) to Fujiko - until the third act. Then the object of everyone’s desire is an artifact that was made by aliens and possesses psychokinetic powers, which we don’t see used in any way, but must exist based on the fact that the Maccherone family is suddenly hot for the doll, and half the police force are sent to protect it.
As you can probably guess at this point, the plot is pure nonsense. But you don’t watch films like this for the plot, you watch it for the gems buried just underneath the skin.
Some of Lupin III’s pratfalls, as performed by Yuki Meguro, are an art unto themselves - with a completely stiff, still body he falls straight back like a cartoon cat recently hit by an anvil. Pure genius. Jigen, played by Kunie Tanaka, is the perfect blend of badass gunman (he packs an entire arsenal underneath his coat, despite the lack of wormholes or other dimensional rifts in the area) and frustrated ninny. But by far my favorite moment in the film is an entire non sequitur - for no reason whatsoever, Lupin III encounters a group of nuns walking the street at night. Perhaps reminded of his youth, he stops to check out the nuns, who lo and behold strip off their habits and break into song. But these singing nuns don’t stop there - nuns, as we all know, don’t fight fair, and these ladies soon surround Lupin III to begin some serious butt-kicking. But Lupin III, breaking all rules of honor in physical combat, parries their kicks and punches with tickling, kisses, and gropes. I watched that part twice. It was truly as amazing as it sounds.
