Luis is traveling through southern Morocco with his son, Esteban. They're searching for his daughter, who has been missing for five months, last seen at a dance festival in the desert. As the pair travel from party to party, they hear of a semi-mythical rave near the border of Mauritania. Descending into the scorched terrain as a not-so-distant global conflict encroaches, Luis and Esteban are soon drawn into a primal landscape in which they must walk a tightrope between heaven and hell.
