It is the year 2025; fourteen years previously wealthy research academic Henderson James had Captain Karl Emmet smuggle a Megasoid to Earth. It is illegal to possess a Megasoid as they are highly dangerous, always thinking about killing, unless in a reproductive cycle, which this one now is. When the Megasoid escapes to hide amongst the stuffed exhibits at a nearby space zoo, James, lacking the courage to track it down and kill it himself, has a clone of himself illegally made for the purpose by clone bootlegger Basil Jerichau. Strict guidelines govern the production of these "duplicates", which must be destroyed before vestigial memory renders them indistinguishable from the originals.
