Aquaman and Aqualad begin investigating the mysterious disappearances of several sea vessels. They witness an ocean liner consumed by a gigantic ship made out of water. They follow the ship's watery descent only to find themselves trapped inside of bubbles of air. They eventually break free and encounter a sorcerer who calls himself Baron Debois. Debois and his colleagues are trapped inside the microscopic confines of a drop of water. Debois befriends Aquaman but quickly turns on him, using his mystical powers to shrink the two in size. The Baron's true name is Merder, and he is a dark sorcerer. He places him within a dungeon in Red Coral Mountain where he meets the crew of a sunken freighter. Aquaman escapes and finds a serum that will return all of the prisoners to normal size. Merder employs his thunder-rod and takes control of all life in the sea. Aquaman discovers that a strong jolt of electricity is enough to free the creatures from Merder's spell. After setting them free, Aqualad and he hide inside the mouth of a whale shark until they can get close enough to Merder to apprehend him. After defeating the evil sorcerer, they use his own technology to return him and his followers to their microscopic prison
