Batman and Robin are called in to pick up the repaired Batmobile. With Falcone watching from the shadows, Earl tells Batman that Marva is "down in the basement", and emphasizes that he has fixed the car's air conditioning switch.
As soon as they drive away, Penguin follows in his own car, taking Marva along as a hostage and leaving Falcone to guard Earl.
Earl has been forced to rig the Batmobile with a remote control held by Penguin. Laughing like a maniac, the Penguin has a fine old time sending the car on a crazy ride, with the Dynamic Duo trapped inside and unable to control it. Batman presses the eject button, but it has been disabled. Finally, Penguin decides to end the game. He drives the Batmobile to the roof of a parking structure and prepares to send them off the edge. Batman realizes that Earl was trying to warn them, as "down in the basement" is a slang term in race car driving for crashing. Remembering what else Earl said, Batman presses the air conditioning switch, and the ejector seats fire, launching him and Robin to safety. The Batmobile goes off the edge and explodes, and Penguin believes he has won.
