This film takes place in the aftermath of the events of JL Drowned Earth. Two years later, Atlantis is still reeling from the devastation caused by the ancient sea demons gods. Aquaman's Trident has been broken as has the spirit of his people. The Atlanteans are angry and threaten to rise up against Arthur. He leaves Orm in charge of Atlantis while he goes on a worldwide adventure to locate magical relics that can repair the divine weapon and restore order to Atlantis. Meanwhile, the rival kingdom of Xebel, led by Mera's sister and figures from her past, invades Atlantis hoping to take advantage of its present disorder. Also, Black Manta begins to plant seeds of doubt in Orm's head and tries to manipulate Atlanna, but ends up falling for her instead.
