Overview: Lupin's date while Fujiko is away is Claudia. Lupin's objective is the gold and silver fortune placed in the mouth of the 100-year Volcano, on Cleo Island. Once every 100 years, the volcano stops erupting, for only 30 minutes. Jigen and Goemon, accepting Claudia's pleas not to steal that which supports the spirit of the natives, attempt to stop Lupin. With the girl and the Mafia also mixed in, who will get the hot fortune?
