On a mission to recover a set of nuclear reactor cores from a research ship, Rex and Six encounter an advanced civilization of marine EVOs.
An EVO sinks a nuclear-powered research ship, but does not harm the crew. Agent Six and Rex are sent in to recover the nuclear rods so they do not do any damage. They end up going to “Trash Island” which is about 537,162 square miles (roughly twice the size of Texas) and was created by the currents sweeping together all the garbage in the oceans. Those very currents also swept up every nanite in the ocean, causing the island to be inhabited by EVOs.
Six and Rex discover an underwater wonder world within Trash Island, which is unexpectedly hollow. It is a city built out of EVO coral and is known as Aquania. Rex and Six get into a fight with various aquatic EVOs led by a Mer-EVO named Serge, but make peace with him at Rex's insistence.
Serge explains that after he turned into an EVO, he discovered a way of controlling the near sapient EVOs and has been using them to convert the normally harmful garbage (such as oil, plastic, etc.) into the coral to build the city.
Things go from bad to worse as the wreckage of the ship falls into an abyss. If it reaches the bottom then the pressure will crush the ship, the fuel rods, and spread nuclear waste across the oceans. Serge and Rex go down to the ship, surviving thanks to their mutual super human durability and retrieve the nuclear rods. Afterwards, Rex and Six promise not to tell anyone of Aquania. After they leave the city, Rex reveals that he took one of the newborn Crustacean EVOs as a gift to Dr. Holiday.
