Zil is an ultra machine chosen to be head of government. It is endowed with every human attribute except one: a sense of humor. Alois Barda is a scientist chosen to lead a group of mutants into exile when the hostility generated by their superior genes forces them to emigrate to another world. How the mutants emancipate the new world to their level; how the relationship between Barda and Zil develops into friendship; and how Zil gets his laugh - are the highlights of this story.
