"Joe Becomes A Master Forger" In the wee hours of the morning a plane flying over London opens doors on its undercarriage and over £1mil in 1-, 5-, and 10-pound notes are dropped. All are forgeries but each are perfect. Joe 90 absorbs the brain pattern of Europe's top forger so he can track down where the fake money is being made and stop the enemy nation out to ruin Britain's economy.
