TERRA NOVA follows an ordinary family embarking on an incredible journey back in time to prehistoric Earth as a small part of a massive experiment to save the human race. In the year 2149 the world is dying. The planet is overdeveloped, overcrowded and overpolluted. With the majority of plant and animal life extinct, devotion to science has brought mankind to the brink of destruction, but has also provided its only hope for salvation. Knowing there is no way to reverse the damage to the planet, a coalition of scientists has managed to open up a fracture in the space-time continuum, creating a portal to prehistoric Earth.
