June 12, 2053 in the Atlantic Ocean, a sea installation is mysteriously destroyed. Admiral Michael Matthews receives a call from the President asking him to take his old job back. Commander Woodie Patterson is sent by the President to escort Matthews back to Pacifica. The nation's gold is being secured at Pacifica.
The death of Bill Holmes means that Matthews doesn't get the warmest of welcomes as he arrives back at Pacifica. He finds a friend with Dr. Raymond Aguila, an aquanoid, a man who has been physically altered so that he is able to breathe under water.
As Matthews takes a tour of Pacifica with Barton, there is an accident at dock 2 of the Pacifica Cargo area causing water to flood in. This is soon followed by another incident where an aquadozer falls on Patterson's aquafoil, trapping the Commander as water rushes in. Patterson is rescued and outside his hospital room, Matthews has to face Lia Holmes who blames him for the death of her husband Bill in similar circumstances.
The President sends Matthews a top secret tape about dangerous earthquakes in the Fort Knox area and their concern for the nation's fissionable H-128 supply, as well as the gold which is being stockpiled in Pacifica. It is Matthews experience with radioactive materials that requires him back in Pacifica to oversee the receipt of the H-128. Matthews urges his brother Brett to speed up preparation of the Pacifica vaults to 24 hours in readiness for the H-128. Someone has other ideas for the very valuable H-128 and a plot to break into the impenetrable vault is hatched.
Dr. Aguila is concerned that the storage of explosive H-128 will turn Pacifica into a military armory. The gold at Fort Knox prevented the H-128 from becoming critical there, so Matthews reassures his team that the same will apply in Pacifica.
Matthews is called to Washington where he learns that the area around Pacifica is threatened by an incoming planetoid which will destroy the underwater city. Matthews has a race against time to get the precious H-128 and gold packed away in the secure vaults and evacuate the city. On his return he learns that the Bill Holmes and Patterson aquafoil incidents were sabotage and realises that they have a double threat to contend with. Matthews devises a plan to use nuclear warheads to try and deflect the planetoid in the hope of saving Pacifica. Will he succeed?
