"It is the twenty-fifth century. People have been reduced to Cerebromorphs - disembodied brains stored in tanks and wired to computers, passing from layer to layer, awaiting liberation at the top level as enlightened beings rehoused in new perfect bodies. But there is one brain that can out-think central intelligence. A brain that engineers a spectacular escape - with bizarre and tragic repercussions for its fellow Cerebromorphs."
