Synopsis

Having failed to defeat Aquaman the first time, Black Manta, still driven by the need to avenge his fathers death, will stop at nothing to take Aquaman down once and for all. This time Black Manta is more formidable than ever before, wielding the power of the mythic Black Trident, which unleashes an ancient and malevolent force. To defeat him, Aquaman will turn to his imprisoned brother Orm, the former King of Atlantis, to forge an unlikely alliance. Together, they must set aside their differences in order to protect their kingdom and save Aquamans family, and the world, from irreversible destruction.All returning to the roles they originated, Jason Momoa plays Arthur Curry/Aquaman, now balancing his duties as both the King of Atlantis and a new father; Patrick Wilson is Orm, Aquamans half-brother and his nemesis, who must now step into a new role as his brothers reluctant ally; Amber Heard is Mera, Atlantis Queen and mother of the heir to the throne; Yahya Abdul-Mateen II is Black Manta, committed more than ever to avenge his fathers death by destroying Aquaman, his family and Atlantis; and Nicole Kidman as Atlanna, a fierce leader and mother with the heart of a warrior.
