When Dr. Director at Global Justice decides that it's the "Ron-ness" that's Kim's secret to success, Ron goes under the microscope. Unfortunately, this means being stolen by the lackey-intolerant Gemini, Dr. Director's older twin. Global Justice, Kim and Rufus take on Gemini's fist of fury (and Pepe the neurotic Chihuahua) to recover the Ron Factor.

Rufus poses as a Peruvian hairless show-dog so that Kim can investigate the mansion of a master jewel thief. Kim agrees to babysit Rufus while Ron is in France for a while. A series of events lead him to become the target of Shego, Duff Killigan, and Monkey Fist when he unknowingly swallows a microchip they're after.
