Black Manta, still driven by the need to avenge his father's death and wielding the power of the mythic Black Trident, will stop at nothing to take Aquaman down once and for all. To defeat him, Aquaman must turn to his imprisoned brother Orm, the former King of Atlantis, to forge an unlikely alliance in order to save the world from irreversible destruction.
Once home to the most advanced civilization on Earth, Atlantis is now an underwater kingdom ruled by the power-hungry King Orm. With a vast army at his disposal, Orm plans to conquer the remaining oceanic people and then the surface world. Standing in his way is Arthur Curry, Orm's half-human, half-Atlantean brother and true heir to the throne.
When his attempt to save his family inadvertently alters the future, Barry Allen becomes trapped in a reality in which General Zod has returned and there are no Super Heroes to turn to. In order to save the world that he is in and return to the future that he knows, Barry's only hope is to race for his life. But will making the ultimate sacrifice be enough to reset the universe?
