While April, May, and June infiltrate Sheldgoose's mansion, the Caballeros trail the villains to Peru. To stop Felldrake from stealing the Nazca Gyroscope, they must enter a mystical land where everything exists only as line drawings.

The Caballeros follow Felldrake to Peru, leaving April, May, and June to sneak into Sheldgoose's mansion, where they find the entrance to his secret wizard's lair. Meanwhile, Xandra leads our heroes to a mystical land under the desert where everything, including the Caballeros, exists as line drawings. They meet Mono the monkey, who tells them Felldrake plans to steal the Nazca Gyroscope, a mystic device that controls the earth's rotation. When our heroes find the gyroscope, Felldrake springs his trap. Then it's a race to the surface, using every weapon they can draw. Thanks to the villains' bickering, Donald, José, and Panchito emerge victorious.—whatsitsgalore

Neither the Caballeros nor Xandra can pass through the magic barrier that surrounds Sheldgoose's mansion. So, while they trail the villains to Peru, April, May, and June infiltrate the mansion to search for the wizard's secret lair.

In Peru, the Caballeros enter a mystic land under the desert where everything, including themselves, exists as line drawings. They find and free a monkey named Mono from a cage created by Sheldgoose, and he explains that the villains plan to destroy the Nazca Gyroscope, a magical device that controls the rotation of the earth. Using his magic chalk to draw his way past obstacles, Mono leads our heroes to the gyroscope, meeting his friend Hanzy on the way.

Meanwhile, April, May, and June are discovered by Sheldgoose's security guards. They are chased all over the mansion, and finally discover the entrance to Lord Felldrake's hidden subterranean lair.

Back in Peru, the Caballeros reach the center of the earth, but are caged by Sheldgoose, who races to the surface to erase the heroes out of existence. Mono reveals that he was tricked into helping the villain but realizes he was wrong. He gives Xandra, Donald, José, and Panchito each a piece of chalk, and, once Hanzy frees them from the cage, they draw their own vehicles to pursue Sheldgoose. The villains release a giant spider to delay the Caballeros, and succeed in erasing Hanzy before our heroes escape the Nazca land. They then draw Hanzy back into existence while Felldrake hatches his next evil scheme.
