500,000 years and more in the future. Disused satellites and space debris orbit around the Earth. Among these there is a structure that resembles a space station. Suddenly a module detaches and crashes onto the planet. After the explosion, we follow an animal that, from the top of a cliff, spreads its wings and flies to the impact site. From the relatively distant readers' point of view, the flying shadow could be a pterodactyl and the Earth we see, in reality, that of prehistory: even the vegetation and the gigantism of the environment would seem to suggest it. Instead, when we get closer to the impact site, the figure becomes more defined: it is a kind of monkey with wings.
The guides in the exploration of this regressed world of the future are
Diego Agrimbau and
Lucas Varela and they use a robot,
Alpha, as their guide. His job is to assist the terrestrial scientist Robert who, together with his wife June, devised a complex plan to repopulate the Earth with
homo sapiens. Robert, in fact, predicting the fate of extinction of human beings, has decided to freeze himself and his wife while waiting for the planet to recover from the ecological disasters left on its surface by the passage of the human race.
