Far away from their home world, a young couple of a highly advanced civilization escape the broken mother ship in a space shuttle, hoping to find a livable planet. They encounter a humanoid species living in their stone age. Using Wrix, the holorobot, they introduce modern technology on the planet. When Wrix is given too much freedom to speed up evolution of the inhabitants, he begins to act like a god. The end result is destruction of the ecosystem. Is there perhaps a Wrix on planet Earth as well?
