Plot In January 1994, the U.S. USS Montana has an encounter with an unidentified submerged object and sinks near the Cayman Trough. With Soviet ships moving in to try to salvage the sub and a hurricane moving over the area, the U.S. government sends a SEAL team to Deep Core, a privately owned experimental underwater drilling platform near the Cayman Trough to use as a base of operations.

Though they treat it with curiosity, Coffey is agitated and cuts it in half by closing a pressure bulkhead on it, causing it to retreat. Realizing that Coffey is suffering paranoia from high-pressure nervous syndrome, the crew spies on him through an ROV, finding
