In the North Atlantic, a massive oil drilling and refining platform named Colossus operates at depths that concern local geologists. To address these doubts, the head of Nexecon Petroleum invites a skeptical journalist to document the facility's safety. During operations, the drill breaches the seabed and opens a fissure into a hidden mirror ocean. This subterranean world contains prehistoric marine life, including the Megalodon, a giant ancient shark that emerges to threaten the crew.
