Hades heeft de vriendin van Hercules naar de onderwereld ontvoerd. Alleen een magische steen kan zijn geliefde nog redden, maar die ligt in het midden in de onderwereld. Hercules gaat op pad om de steen te vinden en zijn geliefde te redden.
Nee, helaas is Ercole al centro della terra nog niet beschikbaar op Netflix in Nederland.
