Earth is no longer what it used to be. An environmental catastrophe has transformed the atmosphere into a large magnifying glass that enhances solar radiation, and a nuclear disaster has slowed down the rotation speed of the planet. Anyone that moves slower than 78 miles per hour will not be able to escape the scorching sun. Only a small group of people was able to survive in this new world, constantly moving in a huge rolling city that can never stop.
