Two dozen people are desperately fighting for life. They are prisoners of the black desert, and leaving the perimeter threatens them with inhuman torment, which is worse than death. Black sand beckons, invisible evil promises salvation, with the onset of dusk it begins to call, and it is almost impossible to resist it. There is no hope of getting out of the death trap. A brutal elimination game is underway, and the rules of this game are dictated by the desert.
