Speeding to Rocky Road, Rhode Island, The Mean Machine shifts into Road Hogger to prevent The Ant Hill Mob and Peter Perfect from passing, and both fall off a cliff. As Penelope Pitstop approaches, Muttley uses a box of chocolates on a fishing pole to snatch her out of The Compact Pussycat. As she dangles, The Convert-a-Car changes to a tandem bicycle to rescue her. Dick Dastardly races ahead to plan some tricks in Big Town.
The Bouldermobile loses a wheel, so The Slag Brothers fetch a nearby rock and pound out a new one, unfortunately square. As the racers enter the city, Lazy Luke and Blubber Bear are amazed at the tall skyscrapers. Dastardly diverts The Arkansas Chug-a-Bug into a subway tunnel, but the train scares him back out and runs over the do-badder. He then erects a phony detour sign to trick all the racers onto the girders of a skyscraper under construction. The Crimson Haybaler flies over its competitors and right off the building. Red Max flaps his arms furiously, but still plummets to the ground. He lands on a bench, catapulting Dastardly to the top. Dastardly runs from The Army Surplus Special and falls, landing in The Compact Pussycat. Penelope pushes the ejection seat button to send him flying to the ground.
Dastardly makes haste as the others continue on the skyscraper. Professor Pat Pending uses Blimp Power to get down. The Slag Brothers pull a gigantic egg from the glove compartment and it hatches, using Pterodactyl Power to fly back to the street. The other racers find their way down too, and the race continues. As the Professor passes, Muttley mans a machine gun, but its force spins him around, riddling The Mean Machine with bullet holes.
As they near the finish line, Dastardly uses Operation K-9 Boom-Boom, shooting Muttley from a cannon to land on The Convert-a-Car in the lead and pour Hot Tamale sauce in its engine. As it falters, Dastardly easily passes. Muttley tries to catch up, but accidentally pulls the engine off The Mean Machine and it coasts to a stop just shy of the line, and The Creepy Coupe takes the win.
