At a depth of 12,000 feet below the surface of the Atlantic Ocean, researchers discover something completely surprising. The greatest archaeological find in history? Or something that humanity has not yet encountered? In an atmosphere of top secrecy, scientists begin to study strange artifacts, but suddenly everyone who works at a research base at the bottom of the ocean is struck by strange diseases. Former military doctor Peter Crane is urgently called to the base, who gradually begins to understand that medical problems are only a small part of a huge problem that threatens the very existence of human civilization.
