After a nuclear war, Earth turned into a desert covered in radioactive dust. Only a few people remain and they eke out a miserable existence in half-ruined cities. Rick Descartes, a professional hunter, receives an assignment to find and destroy several androids that have escaped from an outer colony onto Earth. But little by little Rick begins to wonder: are androids really so different from people? And where exactly does the boundary lie that separates them? The cult novel by the most surprising writer-philosopher—Philip K. Dick!
