(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 ... Goliath must save the kidnapped women of his village from an evil zombie leader who needs their blood to feed his soldiers
