A third energy accident in 2009 transports a number of dinosaurs to that time, tearing a hole in the spacetime fabric. A spacetime meteorite, resulting from the overdrive technology, threatens to bring about a different extinction for the dinosaurs. This causes a skewed timeline that threatens mankindís very existance. To prevent this, a number of dinosaurs from this period are transported three million years beyond 2009, until the crisis has passed. Once it has, the creatures are returned to their own time once more.
