In a dystopian future, humans live among ice and snow. Those who can afford it stay in warm, enormous Dome Cities. Those who can't survive in small villages and gather scrap metal left from the War of the Machines in exchange for food. In one of those villages lives a young boy named Bobo who dreams about flying. He wants to find a legendary "Red Five," an aircraft that, as the legend goes, can bring cures for illnesses and save villages from Dome Soldiers.
