Young Arthur Curry battles a raging polar bear to save an Enuit woman destined to mean a great deal to the adult Aquaman. But the threat of the bear itself is child's play compared to the evil of Nuliajak, the mother of all sea-beasts, and her undersea devil hound. Plus, an appearance by Arthur's brother Orm, the man who would one day be Aquaman's greatest foe...the Ocean Master.
