Plot
Wonder Woman flies to legendary Atlantis, where two queens reign over two nations: Queen Clea of Venturia and Queen Eeras of Aurania. The women of Atlantis are giantesses, and the men (manlings) are puny weaklings. Long ago, Atlantis sank into the sea and was enclosed under the ocean in a pocket of air with phosphorescent rocks on the ceiling for light and warmth, and volcanoes that extend above the ocean for air; many prehistoric creatures extinct in the upper world still exist in Atlantis. Steve, on the trail of a chemical compound, has wound up a prisoner there in the midst of a civil war.
