After a decade of uneasy peace, Atlantis stands on the brink of collapse. A mysterious force from the deep — The Abyssal Order, an ancient cult that worships primordial ocean gods — has awakened a monstrous entity once buried beneath the Mariana Trench. With seaquakes ravaging the surface world and dark storms swallowing whole fleets, Aquaman (Jason Momoa) must forge dangerous new alliances across the Seven Kingdoms to face an evil older than Atlantis itself.

Mera (Amber Heard), now Queen of Xebel, struggles to hold her kingdom together while battling old wounds — political and personal. Her powers grow unstable, linked to a dark prophecy that threatens to turn her into a weapon of destruction.

Meanwhile, Orm (Patrick Wilson) seeks redemption, and Black Manta (Yahya Abdul-Mateen II) returns with upgraded Atlantean tech and a personal vendetta — but even he may be forced to choose between revenge and survival.
