King Orm was raised to put duty to his people above all else. When the Surface Dwellers continue to pollute the once pure and majestic oceans, King Orm decides on war. Vulko always did his best to guide and protect Orm and Arthur like Queen Atlanna requested. But now he feels that he's failing. Vulko's daughter, Nerida, understands his worry and believes that King Orm could be persuaded from war. Nerida must choose between following her king, following her father, or finding a way to save her king without bloodshed so Atlantis may rise once again.
