It's called simply: 'The Aquarium'. It's the world's first underwater zoo. It houses some of the most fearsome, gigantic aquatic predators ever known. Once thought extinct, these living aquatic dinosaurs are now contained in an ultra-secure habitat for public viewing. Marine biologist Nick Lyons and his son have been invited for a sneak preview on the eve of The Aquarium's opening, but when an earthquake disrupts the safeguards of the facility -- all hell breaks loose. Now, Nick and the rest of the guests must brave the dark, dangerous waters and reach the surface... before the primordial beasts reach them. Get ready for sudden depth.
