What is the fate of the man with such a tremendous plan? A millionaire, an undercover agent, community representative, and a genius appraiser that specializes in distinguishing counterfeit bills, speculation is placed on each. Everything leads to a conspiracy of dark organizations trying to destroy the Japanese economy.
