When the Mongols invade Poland, they are defeated for the first time in many years. Kubilai, the commander, asks his emperor, Genghis Khan, for a second chance. He wants to eliminate Maciste, the hero of the Polish people and he holds a prisoner who reveals an important secret: the princess and future queen of Poland lives in a village under a false identity. The Mongols want to capture her, but Maciste, aided by the witch Arias, comes to her rescue.
