In an attempt to take over Gotham City, Egghead pilfers the city charter from its case at City Hall. It seema the city is actually owned by The Mohican Indians and is leased to the city governmant! Every 5 years, the city must pay The Indians - in this case Chief Screaming Chicken, last of The Mohicans - 9 raccoon pelts; 3 pelts from each of the 9 descendants of Gotham City's founders: Pete Savage, Tim Tyler, and our own philanthropist Bruce N. Wayne. If the pelts aren't delivered by midnight on the night of the lease's expiration, the full force of Gotham City will revert back to The Mohicans. Egghead secretly signs a lease with The Chief to act as his legal representative if and when the time on the lease runs out, which Egghead intends to make sure will happen. Batman and Robin trace Egghead to his hideout at The Ghoti-Oeufs Caviar Company and cartch him in the act of negotiating with Screaming Chicken. Egghead bombs The Duo with an egg containing nitrous oxide, and beats a hasty exit with his gang; Batman and Robin later neutralize the gas's aftereffects with Sad Pills.

Later that night, while Bruce Wayne, Richard Grayson, Peter Savage and Timothy Tyler perpare to deliver the raccoon pelts to Chief Screaming Chicken, Egghead kidnaps each and every one of them, with plans of not only preventing the renewal of the city's lease, but to reveal The Batman's secret identity, which he suspects is Bruce Wayne! Planning to eggstract the truth from his mind, Egghead uses one of his goulish devices, which not only will transplant all of Bruce Wayne's knowledge into Egghead's brain, but will leave poor Bruce a mindless fop, too!
