(Contains spoilers) Raiders, attacking the village of Goliath and young Ciro, transport Goliath’s girlfriend, Guja, to the island of Salmanak. Goliath and Ciro follow. Salmanak, nominally ruled by a Sultan, is actually controlled by the vampire, Kobrak. Kobrak has an ally in the villainous Astra, a beautiful woman who exerts influence on the weak-willed Sultan. Meanwhile Goliath allies with Kurtik, leader of the Blue Men. The Sultan’s soldiers soon capture Goliath but he escapes, after rescuing Guja, and together the two flee to a cave in the desert. There they discover the waxed bodies of Kobrak’s victims and reunite with Kurtik. Kobrak arrives, puts Goliath in a pit, encloses him in a bell, and tortures him with sound waves. Goliath survives, thanks to balls of wax in his ears provided by the repentant Astra, but Kobrak succeeds in turning himself into a replica of Goliath. The “bad” Goliath and the “good” Goliath battle. Virtue triumphs, Kobrak’s victims are revived, Kurtik is installed as the new ruler of Salmanak, and grateful citizens erect a giant statue of Goliath while Guja looks on approvingly.
