An energy beam emanating from an undersea crevice causes seaquakes in Atlantis and transforms three surface humans into elemental beings of earth, water and air. Summoned by Aquaman, the Justice League members split up to deal with the threat. Hawkman and Red Tornado are defeated by Air in Midway City; Firestorm, Zatanna and Elongated Man confront Earth in Metropolis to no avail; and Superman, Wonder Woman and Aquaman are stymied by Water near Los Angeles. Discovering the link between the creatures and the seaquakes, the heroes travel together to Atlantis, where they battle the sorcerer Daanuth, a survivor of the original Atlantis who seeks to mystically resurrect his ancient homeland. Superman and Firestorm use stellar energy to return the elementals to normal, causing Daanuth’s powers to ebb, and he disappears into the collapsing ruins of Atlantis.
