Lupin's current target: a key to a certain server facility. Once obtained, the information of all the customers and their funds from the world's largest online bank will be in Lupin's hands. There, they find the developer of the security system of the bank: Amlita. Lupin and Jigen successfully capture Amlita and bring her to their hideout. However, almost immediately upon their arrival, Zenigata and his men surround the place. Being at a loss as to why their location was exposed so easily, they discover an online show going viral. The show's name: "Arrest Lupin III."
