European comics master Alfonso Font presents three satirical science fiction tales, as told by an extraterrestrial, that warn of the dangers that await the human race if it fails to change its ways: a planet so polluted that life on its surface is almost impossible, the human race continuing its destructive and fatal expedition into the galaxy to colonize other planets, humans killed for their organs to transplant into their "superiors", and the keeping of robot companions, whose emotionlessness may be the only way to avoid catastrophe.
