Set in Cheesecago in the 1930s, powerful gangster Al Catone continually menaces the city's inhabitants with his band of thugs and racketeers by cornering the cheese market. With prices now fixed and unreasonable by way of Al's intimidation and extortion tactics, the citizens of Cheesecago fall into despair while city officials are bribed into turning a blind eye to the previously prosperous city's decline. It's up to the Federal Mousehole of Investigation - led by Elliot Mouse, Gordon, and Mr. Wilson - to curb Catone's control over Cheesecago and return reasonably-priced cheese to the hungry inhabitants.
