Hermes is an Argentine anthropologist who is living with the villagers of the Damara ethnic group in Namibia. Researching about the possible origins of mankind and specialized in the cosmogony of some people, he manages to obtain some results. He travel to Argentina searching an answer in San Felix, the last afrodescendant community in the country. Hermes provides a unique bridge that will help to recover the memory of a changed history, with the conviction that mankind descended from amphibious beings. But his desire of knowledge will show him how dangerous it is.
