In this episode, the newly titled, Genghis Khan, sees the Mongol horde explode out of the steppe against China. Then, a chance event leads the Mongols to seek out new plunder from the Middle East as a caravan raid gone bad changes world history. Then, when Genghis Khan dies, a disputed succession leaves the lovable, but drunk, Ogedei Khan in control and badly in need of new conquests. The only question is, which direction should the horde go?
