A father and his son arrive at a rave deep in the mountains of southern Morocco. They’re searching for Mar — daughter and sister — who vanished months ago at one of these endless, sleepless parties. They hand out her photo repeatedly amid electronic music and a raw, foreign sense of freedom. Hope is fading but they push through and follow a group of ravers heading to one last party in the desert. The journey forces them to confront their own limitations as they venture further into the smoldering wilderness.
