When a video-game company creates an immersive gaming environment where players wage war against gigantic sand-dwelling monsters, three gorgeous gals armed to the teeth (Meisa Kuroki, Hinako Saeki and Rinko Kikuchi) accept the challenge and jump into the virtual desert. But as they blaze their way into the game's higher levels, they face ever-more ferocious foes. (official distributor synopsis)
