Episode 20, "Zenigata, Gentleman Thief"
Synopsis: Lupin, Jigen, and Goemon return to small town in Russia where they'd previously pulled a heist, with the intention of grabbing more loot. However, every attempt they make is interrupted by three other thieves, and one is Inspector Zenigata! Apparently Pops, suffering amnesia, is going under the name Monety, and pulling capers to get closer to his lost memories. Is Lupin more concerned with returning his enemy to his normal state or rather outraged by the new competition? It's a trip down memory lane in this competition to be the superior stealer!
