A catastrophic earthquake hits a deep-sea drilling and research facility located seven miles below the ocean's surface, causing massive damage and endangering the lives of the crew. Mechanical engineer Norah Price and her colleagues, including Captain Lucien and biologist Emily Haversham, scramble to evacuate as their survival instincts kick in. Together, they must navigate through the wrecked station, where resources are scarce and every decision could mean life or death.

Facing immense pressure from the crushing underwater environment, the crew is pushed to their physical and psychological limits. Their journey for survival becomes even more perilous when they realize that the quake has unleashed unknown and terrifying creatures. As they move from one compromised section of the facility to another, the threat of these monstrous beings escalates, complicating their mission to find safety. Struggling against time and increasingly dire conditions, they must rely on each other’s strengths and ingenuity for any chance to make it to the surface alive.
