The narrator, who keeps dreaming that he is living in the primordial ages, narrates his exciting adventures and sheds a fascinating light on the early stages of human evolution from his own perspective. This main narrator sees himself as a member of the Cave People group in a world of half-human, half-animal humans.

The Fire People, more advanced than the Cave People, and the less advanced, animalistic Tree People are also a major part of the story. The main character’s father, a woman he is interested in and Red Eye are other important characters. Red Eye is a group of anti-development mischief-makers who constantly cause unrest among the Cave People.

The main character, who has a great narrative power, will allow you to witness this primordial period with your own eyes, thanks to the wise comments he makes both from his own perspective and from an outsider’s point of view.
