Geophysicist Jack Greer believes he has discovered the remains of a meteorite that wiped dinosaurs off the face of the earth sixty million years ago. A few miles off the coast of Yucatán, Jack and a team of researchers use an old floating drilling rig to extract material samples from the bottom of a crater formed by the impact of a celestial body. Underwater, however, an incredible discovery awaits them, capable of upending all our ideas about who we are and where we came from. Quite far from this place, geneticist Dr. Mia Ward receives a mysterious package from Alan Salzburg, her former boss and mentor. The package contains the key to a terrible prophecy encrypted in the human genome and predicting the death of mankind. The instructions in the package are simple: keep the information secret and trust no one. The death of Alan gives his instructions special weight. Who is the author of the prophecy and what does it mean? The answers are in Jack Greer's hands, but will Mia get to him in time? The fate of humanity now depends on this.
