In the aftermath of global thermonuclear war, the Earth’s surface has been turned into a desert battlefield. Three beautiful female hunters: Gray (Meisa Kuroki), Lucifer (Rinko Kikuchi), and Colonel (Hinako Saeki) traverse the barren landscape armed with powerful assault rifles to fight a group of deadly sand-dwelling monsters called “sunakujira” (sand whales). When the the epic battle eventually seems to be coming to an end, the sparkle of muzzle flash dies down and assault ship flies overhead. Suddenly, a gigantic super mutation called “Madara Sunakujira” attacks.
Yup, sounds and looks like Dune.
Well, at least it's directed by Mamoru Oshii of "Ghost in the Shell" fame.
