As Soviet ships and submarines head toward the area in an attempt to salvage the sub, and with a hurricane moving in, the Americans decide that the quickest way to mount a rescue is to insert a SEAL team onto the Deep Core, a privately owned, experimental underwater oil drilling platform, located 1,700 feet (518 meters) below sea level, which will serve as their base of operations.
