- Arthur, Mera, Tula, Garth, and Murk attend the Amnesty Bay Sea Festival in an attempt to broaden their horizons an experience how surface-dwellers live. Arthur reveals to Mera his plans to have Atlantis become an active part of the global community and be less isolated. Meanwhile, an unknown monster who appears wherever water is present is killing random people.
The monster killer who appears from water is not named in this issue, he is identified as Dead Water in issue #50. We can not see what he looks like in this issue, we can only see his clawed hands. In issue #51, we learn that his real name is Jonah Payne.
On the final page of the story, Mera dons a costume similar to Aquaman's and is referred to as Aquawoman in issue #50.
