A group of scientists goes to a depth of seven miles to continue their research in an underwater laboratory. Eventually, something went wrong: power outages and earthquakes. An earthquake disrupts the integrity of the underwater laboratory, and all its employees are trapped. Drilling a well at the bottom of the ocean didn't entail an earthquake at all; an underwater monster began to pursue scientists and opened a real hunt. They must make their way to the nearest station and avoid encountering a sea monster. Lack of oxygen, fear and panic should not stop scientists from seeking underwater shelter.
