The film opens with the statement that the people of Troy must once a month sacrifice a maiden lest a sea monster destroy their city. Because of this, some families flee Troy only to be captured by pirates. Hercules (Gordon Scott), aboard the Olympia, comes across one of these ships and frees the Trojans aboard. Going to Troy, Hercules is given use of two horses that cannot be wounded by arrows. He then learns from Ortag (Roger Browne) the monster's weakness: its armor doesn't cover its belly.
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.
