Ocean Girl – Series Four

Short synopsis

Neri discovers an underwater pyramid, built long ago by voyagers from her own planet. But when her home planet falls to rebels Neri engages in a deadly struggle with a rival Princess for control of the mystical pyramid on Earth, which can save humanity or destroy it.


Neri, with her friends Jason and Brett from the underwater marine station called ORCA, make an amazing new discovery: a pyramid deep beneath the Pacific Ocean. Inside, the statue of a beautiful woman turns into a hologram instructs Neri to begin her journey. The three friends find themselves transported by a mystical “watergate” to the Pyramid of Mystery in the Nile Valley.

Around the same time there are some other curious arrivals in Egypt: Malakat, a professor if Egyptology with his assistant Shersheba, and Jake Shelby and Elly Hauser from the international alien tracking agency known as PRAXIS. Both groups show a disquieting interest in Neri and she and the boys manage to just evade them by reentering the “watergate”, but not before Neri has taken a golden Ankh from the Egyptian Pyramid.

This time the “watergate” transports them to a Crystal Cavern in the Outback, where they meet a new ally, an aboriginal boy called Jakamarra.

Neri gradually discovers that the “watergate” network was established on Earth by Ocean Planet Ancients as part of a colonisation plan which is soon to be put into effect; the hologram is a posthumous message from her mother, queen Shalamorn, and the Ankh is the key to the Underwater Pyramid, which Neri must activate.

But it is revealed that Malakat & Shersheba are themselves aliens from Neri’s home planet, fronting a rebel faction which wants to usurp power and invade Earth prematurely. They must harness the power of the Underwater Pyramid before Neri does. So they betray to the PRAXIS agents that Neri is an alien.

Neri’s attempts to use the Ankh are frustrated by competition from Malakat & Shersheba and pursuit by PRAXIS. The boys make every effort to protect her, aided by the rest of her ORCA “family” including the Bates boy’s hitherto estranged father Paul – and by Jakamarra. But PRAXIS capture her and incarcerate her as a specimen. Elly, sympathetic to her plight, comprises herself as an agent and allows the boys to rescue Neri. But by this time she is all but dead.

Jason and Brett get Neri back to the Underwater Pyramid just ahead of Malakat & Shersheba. The power of the Pyramid revives Neri, but Shersheba shatters the Ankh in fury, whereupon the Pyramid sinks back into the sea. Malakat and Shersheba disappear in defeat, PRAXIS abandon the case and Neri, back on her island, welcomes a return to peace.

But Malakat & Shersheba haven’t given up. Back on the Ocean Planet Malakat has let loose a deadly red virus in the seas, thus making emigration urgent and swelling the rebel numbers by promising an immediate occupation of Earth. Mera, Neri’s sister who has been acting as Regent, is defeated by the rebels and heads for Earth, followed closely by Malakat, Shersheba and the army of commandos.

The Rebel forces occupy the Underwater Pyramid, which has risen again in response to the destruction of Mera’s Ocean Planet power base. But they still need an Ankh to start it. Mera has bought another one with her which Neri and the boys hide.

Malakat, failing to capture Neri, takes Mera prisoner and holds her hostage against Ankh. But now his plans are defected by a bizarre act of Shersheba’s. To force their opponent’s hand, she releases the Red Virus in Earth, unaware that Malakat does not have an antidote.

To Neri’s anguish, Charley is infected with the virus and almost dies.

Aware of the new alien arrivals, PRAXIS return to ORCA, where – endorsed by Madame President of the Global Union – they plan a torpedo assault on the occupied Pyramid.

Malakat obtains the Ankh from Neri by trickery and – unable to stem the virus – puts his invasion plan into action. He starts the Pyramid, intending its power to melt down the ice caps and flood the world. And to ensure secrecy he annexes and seals off ORCA.

By now Shersheba, losing faith in Malakat’s megalomaniacal behaviour, has returned to the Ocean Planet.

Meanwhile Neri and her friends have discovered in Charley’s antibodies a cure for the Red Virus.

But it’s too late to stop Malakat. Neri knows she must penetrate the Pyramid, via the ’watergate’ from the Crystal Cavern, and give the order for the pyramid to self-destruct, even though she will be sacrificing herself. Jason won’t let her go without him.

Neri and Jason comfort Malakat in the Underwater Pyramid. Just as Neri is about to activate a self-destruct button a voice commands her to stop – it is her mother, Shalamorn, who has been liberated by Shersheba.

Mera and Neri embrace their mother in a warm reunion.

Malakat is exiled, and the oceans of the two worlds cured using the natural immunity found in Charley.

Neri is crowned Princess of her people. As Shalamorn predicts that one day both peoples will live together in peace and harmony, Neri is congratulated with a kiss from Jason.

They agree on the need to calm the population and plan a lawful and peaceful migration to Earth should it become necessary.
