A father and son arrive at a rave deep in the mountains of Morocco. They’re searching for Mar–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, they hand out her photo again and again. Hope is fading as they follow a group of ravers to one last party in the desert. As they venture deeper into the burning wilderness, they must confront their own limits on an explosive, white-knuckle journey.
