Plot

In 2050, the Kepler 822, a research and drilling facility operated by Tian Industries at the bottom of the Mariana Trench, is struck by what is assumed to be a strong earthquake. As part of the facility is destroyed by the incident, mechanical engineer Norah Price and her colleagues, Rodrigo and Paul, make their way to the escape pod bay. However, the three discover that all of the escape pods have already been deployed, with Captain Lucien being the only person in the area when the three arrive. Together they reach a control base and find biologist Emily Haversham and engineer Liam Smith, who are unsuccessful in their attempts to make contact with the surface. Lucien suggests using pressurized suits to walk one mile across the ocean floor to Roebuck 641 in the hope of resurfacing from there. As they descend in a freight elevator, Rodrigo's defective helmet implodes under the water pressure, killing him. The surviving crew see a distress beacon from one of the escape pods below, and Smith and Paul go to investigate. As they arrive at the location, they find a body in the rubble. A creature emerges from the corpse's back and attacks them. Smith kills the creature and takes it inside. Haversham examines the creature and realizes that it belongs to a previously undiscovered species.
