The film besieged a group of people in an isolated environment to face the cruel challenge of a foreign object. However, this time the foreign body entered the seabed from space, and the six men and two women working there were massacred in the deep-sea prospecting station.
Sanyo Minerals Company is conducting a 90-day mineral mining activity deep in the Baltic Sea. During the seabed exploration, Baz lost contact with the mother ship and was busy accidentally colliding and finding a sunken ship on the seabed. Crew Elizabeth was ordered to bring Buzz back, and Dr. Thomas confirmed that it was a Russian merchant ship named "Leviathan".
The crew found several volumes of video tapes about the disappearance of the crew and a bottle of vodka in the safe on the Leviathan. For Buzz and others who are negligent of alcohol, the best vodka is more attractive. After getting up the next day, Buzz felt his back discomfort and died strangely 8 hours later. From this, the crew realized that they might have brought back a mysterious and terrifying creature from the Leviathan.
