With microchips implanted in their skulls at birth, the slaves of Cantral and Cillineese have labored under the tyrannical rule of the Nobles and their computers for decades. Monica, a Noble who avoided the implanting and escaped a death sentence at the age of four, is now sixteen and is in hiding. She lives with the slaves inside the walls of the Cantral palace, pretending to be one of them while the slave council plots a way to use her chip-less state to destroy the all-powerful computers that strike down any hint of rebellion. The Nobles hear of Monica's survival and try to exterminate her before she ruins their upper-class utopia. The rebels send her to find a missing paper bearing instructions on how to shut down the computers that control the chips in Cillineese, a major city-state. The Nobles are alerted to the plan and prepare to seal Cillineese in a giant dome to gas the inhabitants, including Monica. The fate of millions rides on Monica's shoulders. As the only chip-less person in the world, she must find the paper, destroy the computers, and free Cillineese from the Nobles' iron fist before they strike with the ultimate punishment-death for everyone inside the city walls.
