Kubilai (Ken Clark), the responsible commander, asks his emperor Genghis Khan for a second chance.

First, he wants to eliminate Maciste (aka Hercules in the American dubbed version), the hero of the Polish people, played by Mark Forest.

And then, Kubilai holds a prisoner who reveals an important secret: the princess and future queen of Poland lives in a village under false identity.

The Mongols want to capture her, but of course, Maciste is a guardian to any maiden in distress... Hercules Against the Barbarians was released in Italy on 16 April 1964.
