NICOLE KIDMAN AQUAMN

In 1985 Maine, lighthouse keeper Thomas Curry rescues Atlanna, the queen of the underwater nation of Atlantis, during a storm. They eventually fall in love and have a son named Arthur, who is born with the power to communicate with marine lifeforms. Atlanna is forced to abandon her family and return to Atlantis, entrusting to her advisor, Nuidis Vulko, the mission of training Arthur. Under Vulko's guidance, Arthur becomes a skilled warrior but rejects Atlantis upon learning that Atlanna was executed for having a half-breed son.

In the present, one year after Steppenwolf's invasion,[N 1] Arthur confronts a group of pirates attempting to hijack a Russian Naval nuclear submarine. Their leader, Jesse Kane, dies during the confrontation while his son, David, vows revenge. David later targets Atlantis at the behest of Orm, Arthur's younger half-brother and Atlantis' incumbent monarch who uses the attack as a pretext to declare war on the surface world. King Nereus of Xebel swears allegiance to Orm's cause, but his daughter Mera, who has been betrothed to Orm, refuses to aid them and journeys to the surface to ask Arthur for help, earning his trust by saving Thomas from a tsunami sent by Orm. Arthur reluctantly accompanies Mera to a rendezvous with Vulko, who urges Arthur to find the Trident of Atlan, a magic artifact that once belonged to Atlantis' first ruler, in order to reclaim his rightful place as king. They are ambushed by Orm's men and Mera and Vulko escape without having been seen, while Arthur is captured.

Arthur is chained and presented before Orm, who blames Arthur and the surface for Atlanna's death. He offers Arthur an opportunity to leave forever, but Arthur instead challenges him to a duel in a ring of underwater lava. Orm gains the upper hand and nearly kills Arthur before Mera rescues him. Together, Arthur and Mera journey to the Sahara desert where the trident was forged and unlock a holographic message that leads them to Sicily, Italy, where they retrieve the trident's coordinates. Meanwhile, Orm provides David with a prototype Atlantean battle suit to kill Arthur, imprisons Vulko after revealing knowledge of his betrayal, and coerces the remaining kingdoms of Atlantis to pledge their allegiance to him and his campaign against the surface.
