The Super Friends must stop the plans of a conqueror named Torhana who seeks vengeance on the people of the surface world by freezing everything in his path. Torhana and his crew travel by ship, freezing oceans and continents and people... Aquaman uses his telepathy to summon sword-fish to cut him out of the ice and take him to Atlantis. Torhana and his crew appear to have the upper hand but by episode's end the Super Friends regroup and come up with a clever plan to melt all of the ice that's engulfed the planet. This is one of the few episodes in the series that features Aquaman at his usual base of operations in the comic books: the undersea city of Atlantis.
