The Enemy Below Part 1
When another nuclear submarine violates the Atlantean space tension between Atlantis and the surface boils up into near war. The Justice League has its own opinions on the situation and on Aquaman himself, King of the Atlanteans. Aquaman tries, kind of, to reach out a hand in peace, but he’s attacked and nearly killed. The Justice League sets up a trap for the potential assassin, but Aquaman himself can’t sit by and do nothing.
Meanwhile Atlantis believes their king dead and Aquaman’s brother prepares to lead them to invade.
