Experiment #657

Following new reports of strange crypto activity, a team of investigators venture into the infamous Fossil Valley, where dinosaurs attacked a group of people 30 years ago. Once there, they are transported into a lost world of Jurassic monsters they will have to battle in order to survive and get home again.

In a world gone mad, the last human colony struggles to survive underground, beneath a land of nightmarish mutants who seek to destroy them. But when the mutant breaks inside humanity's final stronghold, the battle for survival pits the human colonists against their deadly invaders miles below the earth's surface.
