Devon, Rachel, and Garth are lured into a dome where the inhabitants are trapped in a highly industriaiized, hell-bent-for-leather society which is choking itself to death on its own noxious effluents; the purification and filtering system of the dome simply cannot keep up with the mad pace these people have set for themselves. The leader of the Liverpudlians is Mr. Smith, an absolute ruler who knows his people would displace him if he took the hard but necessary decision to simplify their lifestyle. Smith is finally overthrown and the poliutive machines stilled as our three push onward.
