There are parts of the ocean even Aquaman should not enter. Now Aquaman and Mera must descend into uncharted territory: the smoky black crevice at the bottom of the Atlantic Ocean, home of the cannibalistic creatures known only as the Trench. One last secret behind these loathsome creatures will be revealed as "The Trench" thunders toward its bloodcurdling conclusion!
In order to seal the Trench to stop them from invading the surface world again, Aquaman triggers a volcanic eruption. The queen of these subterranean beings dies in the process. Back at Amnesty Bay, Aquaman helps the people who were trapped in the cocoons the Trench made to preserve their "food". A boy comes up to the Sea King and tells him that
Aquaman is his favorite super hero, bringing a smile to both him and Mera. Later at the Curry Lighthouse, deputy Wilson arrives to thank Aquaman and Mera for their help and to apologize for the action of some of his colleagues. Someone else wanted to say thank you and it was the dog that Aquaman rescued. The aqua duo decide to keep the dog and realized he needed a name. Deputy Wilson suggested Aquadog. The story ends with Mera saying they will have to teach their new pet to swim.
There is an Epilogue to the next story line that shows the continent of Atlantis being sunk in one day. Aquaman will begin a quest to solve the mystery.
