In the middle of the South Pacific, 1,000 feet below the surface, a huge spaceship is discovered resting on the ocean floor. It is a craft of phenomenal dimensions, it seems undamaged by its fall from the sky, and it appears to be at least three hundred years old. Rushed to the scene is a group of American scientists who investigate this astonishing discovery. What they find defies imaginations and mocks their attempts at logical explanation. Now a major motion picture directed by Barry Levinson and starring Sharon Stone, Dustin Hoffman, and Samuel L. Jackson.
