From the introduction: You are nomads in a post-apocalyptic wasteland whose water purifier has been stolen. Men killed the world with atom bombs, turned the seas from water to salt, and left the ruins buried in radioactive sand. Your water purifier as the key to pure aqua cola, and it's been broken up and stolen by a bunch of fetish-wearing raider-thieves. Armed with your vehicle and whatever you can find, ride across the broken earth, and be witnessed!
