Geophysicist Jack Greer believes he has discovered the remains of a meteorite that wiped out the dinosaurs from the face of the earth sixty million years ago. A few miles off the coast of Yucatan, Jack and a team of researchers use an old floating drilling rig to extract samples of materials from the floor of a crater created by the impact of a celestial body. However, an incredible discovery awaits them underwater, one that can change all our ideas about who we are and where we come 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 humanity. The instructions in the package are simple: keep the information secret and don't trust anyone. Alan's death gives his instructions special weight. Who is the author of the prophecy and what does it mean? The answers lie in Jack Greer's hands, but will Mia have time to get to him? The fate of humanity now depends on this.
