The year was 2066, the world had fallen into ruin and chaos once again. The Germany war machine has started up again, now the government is plotting to take over the world. Little was planned to stop them, now they have conquered Europe. To exercise their power, they've built walls around their kingdom, surrounding it in cobble and steel, enforcing rules with fists of iron. There were three walls, the inner, middle and outer. Those in the inner were the high-class, the government. The middle housed the military, while the outer was for the peasants and prisoners of war. The Inner gorge themselves on food, the Middle trains soldiers and torture prisoners, while the Outer, is filled with farmers and workers, who suffer the worse punishment. The prisoners of the Middle and the workers and farmers of the Outer have strapped to their necks, metal shackles, designed to track the number of steps they are supposed to take. If exceeded, the shackles will detonate immediately, killing them. The Inner's Government controls the number of steps given out to the rest of the circles. All diplomatic efforts were crushed and now Russia and the US have no choice but to commence an underground coo just to undermine the German government. This story follows three boys and one girl, and their fight for freedom.
