Deep in the mountains of southern Morocco, a father (Sergi López) and his son, Esteban (Bruno Núñez Arjona), arrive at a rave. They are searching for Mar - their daughter and sister - who vanished months ago at one of these endless, sleepless parties. Surrounded by electronic music and a raw, unfamiliar sense of freedom, again and again they hand out her photo. Hope is fading, but they push through and follow a group of revelers heading to one last party in the desert. As they venture deeper into the burning wilderness, the journey forces them to confront their own limits.
