La vendetta di Ercole
The film begins with Hercules/Goliath/Emilius entering the underworld and defeating several monsters including Cerberus to retrieve the Blood Diamond of the Goddess of Vengeance. It is later revealed that King Eurystheus has sent Hercules/Goliath on this task to ensure his death to gain allies who after Hercules' death will join the King in an attack on Thebes. The episode is loosely based on the twelfth of the Labours of Hercules.
Hercules returns to his wife Deianira to find that his teenaged son (his brother in the American version) Hyllus is in love with Thea the daughter of a King that Hercules believes murdered his family. The enraged Hercules refuses to let Hyllus have anything to do with Thea. The scheming Eurystheus has convinced Hyllus that Thea is really in love with Hercules rather than him and concocts a plan where a jealous Hyllus will murder his own brother. A slave girl Alcinoe gives Hyllus a poison to give to Hercules that she says is merely a potion to have Hercules fall out of love with Thea. Eurystheus himself wishes to marry Thea and install her as his Queen.
The plan is aborted through a sympathetic Goddess of the Wind who relays Thea's warning. Hyllus attempts to rescue Thea but is captured. When Hercules rides to rescue Hyllus he saves the life of Alcinoe who is menaced by a bear. Ilus is to be executed with others in a public display by being crushed by an elephant in a crowded arena. Hercules rescues him.
On their return home the two are given a prophecy that Hyllus will become a King but at the cost of the life of the woman who loves Hercules. Hercules destroys his home and leaves with his family to try and avert the prophecy. Dejanira offers her life to the Gods in order to fulfil the prophecy for Hyllus. She is carried off by a Centaur corresponding with Nessus who Hercules mortally wounds.
The Centaur is able to bring his captive Deianira to his friend Eurystheus who intends firstly to let her be killed by his dragon, then to act as a hostage against the vengeance of Hercules.
