Anime Episode guide, Chapter Lupin III Season 2 Episode 20 English dubbed Lupin Up Against the Wall. Setting his sights on the large medallion on Generalissimo Hatler’s chest, which contains a 50-carat ruby, Lupin should have been able to take it easily enough, using his special rod-and-reel technique, but ends up exposing the Generalissimo’s secret toupee instead when the wind blows the hook on his fishing line over Hatler’s head instead of the jewel. The infuriated Hatler orders that Lupin and company be wiped out, and in the face of the attack by his combined armed forces, a wounded Lupin makes his stand in an old castle with Fujiko while Jigen and Goemon attempt to save them.
