Inspired by the investigation of the French ethnologist Marcel Griaule, Hermes, an Argentinean anthropologist, is preparing his first stage play. Fascinated by ancient knowledge from Dogon and Tchokwe ethnic groups, Hermes dreams with recovering the information about the possible origin of mankind, created by amphibious beings, which proceed from other places of the universe. With the help of Oko (an Angolan young) , Ayelen (the leading actress of his play) and Esteban (an Egyptologist), Hermes travels to Angola and Ethiopia in search of the last wise men, with the purpose of obtaining the answers.
