Lupin finds out from a young girl that the Nazis buried a secret treasure before being caught. He and his companions Jigen and Goemon embark a crusade in North Africa to find it; however, his lover/rival Margot Miné made an allegiance with Helmut von Pfefferman, a German count who is a distant relative of the commanding officer who buried the gold. On the location, Lupin and Pfefferman find out alike that the hiding place was actually a launch base for spaceships: the Nazis left Earth with their gold and flew to the Moon! Pfefferman shoots Lupin and, thinking to have killed him, starts a mission to rescue the gold on the Moon. (Go to the comments for the rest of the story)
