Lupin the 3rd: Is the Invader Safe Open?

Overview

While walking around New York City's downtown area, where Jigen grew up, Catherine, an old acquaintance who is now the widow of a diamond broker, issues a challenge: "Can you steal my jewelry?" Jigen goes, reluctantly, with Lupin and Goemon tagging along, but security is tighter than tight, and a half-baked effort will not suffice. The final Space Invader Safe is itself a major obstacle, but there is no time remaining to Catherine.
