Plot
1000 feet below the ocean, navy divers discover an object half-a-mile long. A crack team of scientists are deployed to the site in Deepsea Habitats. What they find boggles the mind as they discover a perfect metal sphere. What is the secret behind the sphere? Will they survive the mysterious 'manifestations'? Who or what is creating these? They may never live to find out.
In the middle of the South Pacific, a thousand feet below the surface of the water, a huge vessel rests on the ocean floor. Rushed to the scene is a group of American scientists who descend to the depths of the sea to investigate this astonishing discovery. What they find defies their imaginations and mocks their attempts at logical explanation. It is a massive spaceship, undamaged from its fall from the sky—and at least three hundred years old.
