A father and his son arrive at a remote rave in the middle of the mountains of southern Morocco. They are looking for Mar, their daughter or sister, who disappeared months ago at one of those never-ending, sleepless parties. Surrounded by electronic music and a raw, unfamiliar feeling of freedom, they show their photo around again and again. Hope fades, but they don't give up the search and follow a group of ravers to a last party in the desert. The deeper they go into the scorching wilderness, the more the journey forces them to face their own limits.
