The story arc consists of six issues from DC's Justice League and Aquaman publications,[1] functioning in part as a larger buildup towards the "Trinity War" event.

Aquaman's allegiances are torn between his brother and the Justice League, while the latter group finds itself overwhelmed as the East Coast of the United States is swallowed by the ocean and the Atlantean royal troops march against humankind.

A Navy warship incites the wrath of the Atlanteans after its missiles malfunction during a test and end up attacking Atlantis.

While they are in a café in Metropolis, Superman and Wonder Woman are forced to suit up and stop an aircraft carrier from flooding into the city and killing thousands of people.

The heroes stop Ocean Master and figure out that Aquaman's assistant Nuidis Vulko was behind the bombing so Arthur would take the throne once again.
