What Lupin the Third: Goodbye Partner is
It is a brave animated caper that dares to ask: what if Lupin wasn't the one in trouble with the law for once? When Zenigata is suspected of colluding with Lupin, Lupin attempts to clear his name. However, Lupin must also contend with a partner's unexpected betrayal. It's certainly a plot.
