The galaxy is recovering from the trauma caused by the emergence, ten years ago, of the Collectors, robots of the size of a planet that foreshadowed the revolt of machines against men. It is in this world in the midst of reconstruction, which has since learned to hate the mechanical genre, that Tim-21 awakens. Without knowing it, the little droid hides in his printed circuits the legacy and the true intentions of the Collectors. A secret that all the governments of the galaxy would dream of seizing.
