Hermes is an Argentinean anthropologist who is living with the members of a damara village in Namibia. Looking for information about the knowledge that has been transmitted orally from shaman to shaman for thousands of years, Hermes believes he can find a mystery related to the power of sound. But an unfortunate contact with foreign members of a secret lodge linked to a laboratory of back-meteorological experimentation, will present him with a setback in his path to enlightenment.
